I am a proofreader, an editor, and an English as a Second Language (ESL) instructor/tutor. I have been certified as an ESL instructor since 2003, and from 2003 - 2007 I taught English and developed course curriculum in Malaysia. I have served as a tutor with Wyzant since April 2013, and a significant percentage of my work has involved proofreading and editing. For book or long article editing, my asking rate is $4 per page, with a page defined as 250 words. My rate is negotiable.
