I am a native English speaker. I have my Bachelors Degree in English Education. I have been teaching for over 14 years, so I proofread, edit and give feedback on a daily basis. I charge $.005 USD (half a penny) per word, plus the freelancer fee. I have extensive proofreading experience, including articles, fiction novels, legal documents, business plans, and master thesis papers, among others.
I would be interested in hearing more about your book and what you feel you need the most focus on.
