Hi. I´d like to help you edit your article, proofreading the English, revising the structure and clarity of expression (if needed), and researching the historical data you mentioned. Although I live in Brazil now, I´m an American editor and proofreader, a native English speaker with excellent language skills and years of experience at correcting and improving books and other texts. I use Word´s Track Changes to show you all my corrections, comments and questions in your text, and always offer suggestions about how to improve what you´ve written without interfering in your own personal writing style. I also offer a 2nd revision - after reading and commenting on your text, I send it back to you to see if you want to make adjustments based on my observations - then you return it to me for a final revision of those adjusted parts. I need an idea of the size of the article to calculate how long it will take to finish. Please contact me for further discussion, I can start as soon as I´m hired. Thanks, David
