    Experienced, meticulous proofreader

    United Kingdom - Last active: 21 days ago - Portfolio: 9

    I am a perfectionist English proofreader with a wealth of experience in a wide range of material, including fiction and non-fiction books, articles, web copy, and - in particular - academic papers such as theses and dissertations. I work with both native speakers, and those for whom English is their second language. I am passionate about the written word and helping to create text which is fluent, clear, and a pleasure to read. Proofreading is, by necessity, slow and meticulous work, and I never 'cut corners', get software packages to do the work for me, or speed-read scripts. Over the years, I have also acquired strong copy-editing skills; I routinely check for inconsistency, unnecessary repetition, contradiction, or shifts in style. Throughout the editing process, however,I remain sensitive at all times to the 'voice' and intention of the author. In brief: I am reliable, communicative, skilled and dedicated - and have never yet missed a deadline!

    United States - Last active: 3 days ago - Tests: 2 - Portfolio: 5

    I have been teaching high school English for 20 years. I can write about practically anything. As a high school teacher and writer, I have a solid grasp of grammar and style. I have been teaching writing, and editing student work for many years. I discovered Elance by accident, but I have found it to be great place to be able to write, meet clients, and develop business relationships to meet their needs in an online setting. It has given me a new perspective as a teacher about the importance of writing and communicating. Over the years as a teacher, I have taught practically every subject, from creative writing to American Literature to Mythology. I also advised the school yearbook for several years and my books were awarded top marks in yearbook competitions, with one of them receiving international recognition for its quality and design. I have a BA in English and a MA in Education and I have taken many Master's level courses in journalism.

    “Fantastic voice over and amazing turn around time. What more could I ask for?” “Great work! First voice over service I used that does NOT require any edits. Perfect to the T! Will definitely use again and recommend to anyone.” I have spent my entire life using my voice to entertain, educate, and train others.
