Hi. I can proofread your text, whether it was originally written in English or has been translated from another language, correcting the grammar, spelling, vocabulary, punctuation and sentence structure. Although I live in Brazil now, I´m an American writer, researcher and editor, a native English speaker with excellent writing skills and years of experience at correcting and improving what someone else has written. I can use Word´s Track Changes function to show you my corrections, comments and suggestions for your text. I can proofread 50 pages in 10 days (probably less, but I have other commitments, permanent clients, etc. which take up part of my time), for $200. Please contact me for further discussion, and let´s put the finishing touches on your project. Best, David
