Do you want to learn how to start a proofreading business?

Proofreaders add the final polish to written content: blog posts, website copy, marketing materials, resumes and cover letters, academic papers, legal briefs, and much more.

This is a highly flexible side hustle and an excellent fit if you enjoy reading or have a knack for catching grammar and punctuation mistakes.

Today I’m sharing an interview with Ariel Gardner, a proofreader, copy editor, and freelance writer who has edited for me for nearly seven years.

Ariel began proofreading as a side hustle and turned it into a flexible full-time career that lets her travel with her family in the summer. She went from earning less than $500 a month to regularly making $4,000 or more each month.

In this interview, Ariel answers practical questions about how to start a proofreading business.

Proofreaders are in demand because business owners need error-free content, and—as Ariel explains—search engines favor accurate, well-written pages. If you’re considering a flexible, in-demand side hustle, Ariel covers the questions most beginners ask, such as:

• What’s the difference between an editor and a proofreader?
• How much do proofreaders earn?
• How long does it take to become a proofreader?
• How can a new proofreader build their portfolio?
• How can a proofreader find paying clients?
• Do you need a degree to become a proofreader?

Plus more practical tips to help you get started as a paid proofreader.

If you want to launch a proofreading business alongside a job, while you’re in school, or with children at home, this interview is a helpful place to begin.

How To Start A Proofreading Business

Hello! Can you share your background, who you are, etc.? How did you start your proofreading business?

Hi—I’m Ariel Gardner. I’ve worked as a freelance proofreader, copy editor, and writer for about seven years.

Proofreading and editing have been part of my life since high school. I served as editor-in-chief of my yearbook and spent many hours fixing classmates’ articles. That role gave me an early chance to apply and refine my skills.

My grandfather, an English professor, also influenced me—he corrected grammar at the dinner table and taught me an important lesson: it’s okay to break the rules once you understand them. Writers make stylistic choices that shape tone and meaning, and recognizing that helps you work with a wider range of clients.

My proofreading business began in college while finishing a bachelor’s degree in English. Juggling two jobs and three children, I first volunteered proofreading services for my son’s preschool and later did small paid editing projects. Around that time, I began working with Michelle and editing her blog posts. Those early monthly payments—$300 to $500—made a real difference.

After a few years of juggling multiple jobs, two pivotal events happened: my father passed away, and I graduated. His passing allowed us to sell his house and pay off ours, which gave me the breathing room to try turning my side hustle into full-time work for a summer. I built a simple website and pitched anyone who might need my services.

That effort paid off: I landed projects proofreading and formatting poetry collections, working with a nonprofit, and editing website copy. I continued expanding my skills and services and eventually secured recurring work with sites like Millennial Money Man and Laptop Empires, helping with weekly proofreading, copy editing, and writing.

Within about six months, I was regularly earning $4,000–$5,000 a month and was able to quit my part-time jobs. I worked as an independent contractor until early 2022 when I accepted a salaried position at Millennial Money Man. Today I have a flexible role that still lets me teach others how to start proofreading and editing.

What’s the difference between a copy editor and a proofreader?

Copy editors improve the content’s clarity, flow, and overall style. They correct grammar and punctuation, ensure consistency and concision, and can restructure sentences or rephrase text. Copy editors often make larger stylistic or structural changes as needed.

Proofreaders focus on surface-level errors—spelling, grammar, punctuation, and consistency in formatting (fonts, italics, bold, etc.).

Typically, the workflow is: author, copy editor, then proofreader. But not every project needs both roles; many clients only need one.

How much money do proofreaders earn?

New proofreaders usually earn about $15–$25 per hour. With experience or a niche, rates can rise to $30–$50 per hour or more.

High-paying niches include science, technology, and medicine, which require familiarity with specialized terminology and style guides. Proofreading resumes, CVs, and cover letters can also be lucrative—some clients will pay $200 or more for an in-depth review because of the tight turnaround and high stakes.

Are proofreaders in demand?

Yes. Many business owners underestimate how much proofreading improves professional copy. Proofreaders can work on web pages, sales pages, emails, white papers, academic articles, ebooks, screenplays, grants, resumes, and more.

As more content is published online, demand grows. Google and other search engines favor accurate, error-free content, so site owners who want better search visibility benefit from proofreading or copy editing.

How can a new proofreader build their portfolio?

A straightforward way to build a portfolio is to offer free services to someone in your close network. This provides experience, confidence, and a testimonial—valuable assets for new proofreaders.

After a first completed job, use that work and reference to pursue paid work. Two practical approaches are: find jobs on freelancing platforms like Upwork or pitch potential clients in your extended network.

Start small with lower-paying projects and scale up as you develop a niche, build expertise, and expand your portfolio.

How long does it take to become a proofreader?

Time to get started varies. Some people already have sharp proofreading skills and mainly need help finding clients. Others may need to refresh techniques or learn style guides.

In most cases, you can secure your first client within a month if you actively pursue opportunities. The biggest barrier is often confidence—putting yourself out there and accepting that you’ll hear “No” sometimes is part of the process.

How does a proofreader find paying clients?

There are many strategies: offer services to friends and family, use freelancing platforms, network in Facebook groups and local business organizations, or pursue direct outreach.

A favorite outreach technique is the “I found an error on your website” pitch. When you find a spelling, punctuation, or grammatical error on a site, screenshot it and send a brief, professional message showing the error and a suggested correction. Include an offer to proofread more of the site. This approach demonstrates value and positions you as an immediate solution.

What skills do you need to be a proofreader?

Proofreading requires two types of skills:

• Technical skills: the ability to spot and correct errors, a solid grasp of grammar and punctuation, and familiarity with style guides.
• Business skills: marketing, client communication, project management, and relationship building—skills needed for any freelance career.

Do you need a degree to become a proofreader?

No degree is required to work as a freelance proofreader. Some positions at larger firms may ask for formal qualifications, but most freelance clients care about skill and experience.

That said, a degree can help you qualify for certain niches. For example, a STEM degree makes you a better fit for editing scientific journals, textbooks, or research papers in that field. If you have relevant academic or professional experience, highlight it on your profiles and pitches.

Can you work from home as a proofreader? Is this a good freelance career?

Absolutely. Proofreading is an ideal work-from-home career and can also be done while traveling. The job is flexible—many proofreaders work remotely full time or part time and arrange schedules around family or travel.

Proofreading offers both one-off projects and recurring work, enabling freelancers to build long-term client relationships while taking on new, varied assignments. Over time, you can expand services from general proofreading to copy editing, manuscript editing, or specialized niches.

What specific steps does a person need to take to make money proofreading?

Start by refreshing your proofreading skills. Pay attention to content you read—books, articles, social media—and note how you would fix errors. This practice sharpens your eye.

Next, learn how to find clients. Choose one or two prospecting strategies—freelance platforms, direct outreach, or networking—and focus on mastering them instead of trying everything at once.

Avoid getting bogged down in business formalities early on. You don’t need a perfect website, an LLC, or a business bank account to begin—focus first on finding paying clients. Offer to proofread a friend’s resume, pitch a small business you know, or use the outreach method described above.

Essentially, the two core steps are: refresh your skills and find clients. You can expand those into smaller, actionable steps as you grow—topics covered in more depth in courses like Proofreading Launchpad.

Last, are there any other tips you have for someone who wants to learn how to start a proofreading business?

My main tip is to stay out of your own way. Fear of rejection or worries that you’re not good enough can prevent you from pitching and finding clients. That fear is natural, but it’s usually an ego response—not a real threat.

Accept that some pitches will get “No” and that this is part of the process. The sooner you move past fear and start pitching consistently, the sooner you’ll find clients who say “Yes.”
