David & Sharon Cox

My name is David Cox. My wife, Sharon, and I are the co-owners of TPB Business Copyediting. Together, we specialize in providing copyediting services to improve your business’s work product, administrative documents, and online content.

As Copy Editors, we provide these services remotely from our home office in Central Illinois. Thus, we can deliver reliable, quality services for you at an affordable, flat-rate price.

You may feel that your business’s written content needs a more consistent, polished, and professional appearance. If you would like to accomplish this objective but need to devote your time to other essential functions—contact us. I assure you, we can help.

What We Do

Since your written content represents you and your business, we strive to enhance your credibility and reputation by improving your work product, administrative documents, and online content.

We copyedit almost every type of written content associated with businesses, including but not limited to the following:

  • Advertising copy
  • Blog articles and posts
  • Business letters
  • Business plans
  • Business proposals
  • Business reports
  • Case studies
  • Company profiles
  • Emails
  • Employee handbooks
  • Grant narratives
  • Internal business documents
  • Job applications
  • Job descriptions
  • Job posts
  • Marketing materials
  • Newsletters
  • PowerPoint presentations
  • Press releases
  • Product descriptions
  • Requests for proposals (RFPs)
  • Service descriptions
  • Training materials
  • Website content

Why Our Services Matter

  • The written content you produce and share with peers and prospective clients is often the basis for their first impression of you and your business. In other words, anything written for your business represents you, your credibility, and your reputation.
  • Although there is wide acceptance of informal texting, acronyms, and verbal slang, your grammar skills will set you apart favorably in professional settings.
  • In essence, good grammar is a trust signal that says, “I do good work,” and makes others feel more confident in buying from you or retaining your services. Errors in grammar, spelling, and punctuation can embarrass you and harm your business’s credibility.
  • People will judge your competence and intelligence based on your proper use of the English language, whether they realize it or not — and regardless of whether you feel it’s fair for them to do so.

How We Do It


All copyediting and proofreading assignments, no matter how large or small, pass through two editors to ensure that we:

  1. Find and correct grammar, spelling, and punctuation errors
  2. Enhance accuracy and readability for your audience
  3. Find and correct spacing errors and dropped words
  4. Resolve sentence fragments
  5. Revise “run-on” or “sprawling” sentences
  6. Correct errors in word usage (e.g., advise/advice, effect/affect, there/their/they’re, etc.)
  7. Remove redundant words and phrases
  8. Apply SEO standards to the written content for your website and social media pages

It’s about You. Your credibility. Your reputation.

We at TPB understand your situation. You bring leadership and value to your business every day in areas that you can’t outsource.

Unquestionably, these are the areas where you need to devote your time and energy.

Let’s face it; you’re good at what you do. You’ve also probably made a significant financial investment to get where you are today. Thus, you want the written content that comes from your business to represent your competence and professionalism.

If you contract with us, we will use our expertise as Copy Editors to ensure that the writing for your work product, administrative documents, and online content enhances your credibility and reputation.

The TPB Copyediting Team

David CoxBusiness Copy Editor | Co-owner

I have devoted over 30 years to career roles that involved writing, copyediting, and proofreading. Additionally, I have helped numerous clients improve their print and online written content since Sharon and I launched our business four years ago.

I am a career generalist, having served as a retail sales manager, a public school teacher, and a minister. I’ve also served as a general manager for an Internet Service Provider and later as a human resource director for a rural telecommunications company.

Throughout my career, I’ve written numerous articles for professional and trade publications. I’ve also written over 230 blog articles and posts and hundreds of newsletter articles.

Furthermore, I’ve written three curriculum guides and authored eight seminars (extensive PowerPoint presentations) on employee development, which I’ve presented for staff and in-service training throughout Central Illinois.

Additionally, I served as the general Copy Editor for the book Dementia Action Plan: How to Give Your Brain a Fighting Chance, by Hamid Reza Sagha, M.D.

Sharon CoxBusiness Copy Editor | Co-owner

I have worked as an executive assistant for over 30 years in secondary and higher education, rural telecommunications, and county government. These positions afforded significant experience in writing, copyediting, and proofreading.

David and I share a love of the written word and place a high value on persuasive and accurate written communication. Additionally, we have great respect for small business owners and American workers, especially in this ever-changing and increasingly challenging world.

We are excited about helping you achieve your business and career goals by strengthening the print and online written content representing your business to the world.

David and I embraced life in Central Illinois 25 years ago, making a home in Lovington, Illinois, and raising three children. We are proud parents of a son and two daughters and grandparents to four beautiful granddaughters.

As I close one chapter, retiring from my current county government position, I look forward to putting my energy into our business by helping people achieve more effective written communication.
