I am a former University Maths and Computer Science academic with 13 published research papers. On the basis of the quality of my writing, I was offered work 6 years ago as the copy editor for a journal. Since that time, I have accumulated 6 years of experience in copy editing, proofreading and rewriting a variety of documents. These have included books, articles, resumes, dissertations, correspondence and web sites. I usually charge $5 for editing one 250 word page (which is roughly one double spaced a4 page), so 1000 words would come in at $20. This charge includes editing your documents 3 times, and corresponding with you to clarify any issues that may arise, and to make sure you are happy witht he final product.
I am a native English speaker, based in Sydney. Although I have previously completed graduate studies in Mathematics, I am currently working towards an undergraduate degree in Music and Archaeology.
