I am interested in your project but you haven't stated how many words/pages, so I may have to adjust my bid price and time frame accordingly.
I registered with Freelancer in February last year and have 53 reviews, all positive. English is my first language and my skills include technical writing, editing and proofreading.
I have ongoing freelance work editing papers for an online journal for translators and interpreters.
I recently edited a 65,000-word science fiction novel and the client was so pleased with my work that he commended me to Freelancer - and an article about me has recently been published https://www.freelancer.com/community/articles/57-year-old-discovers-a-lucrative-career-on-freelancer-com
Other recent work has included proofreading six theses on a variety of subjects, as well as individual chapters of academic writing.
For two years I was a copy editor for Elsevier Science Publishers in Amsterdam, the Netherlands, rewriting text by authors who were not native English speakers.
I have worked with individual clients to bring 15 books to publication and three of these clients have rehired me to work on a second book.
Having been a teacher of English in high school for several years, I have spent many hours making corrections and suggestions for students' essays. For an additional two years I was a teacher of English as a second language.
