Hello. I've bid to proofread (spelling and grammar check) approximately 5,000 words of web copy for perfect English. I can provide you with an error-free text - depending on format, I can give you a track changes Word copy. I am a native US English speaker with a master's degree in writing. I frequently proofread web copy of various subject and interest, as well as highly technical PhD dissertations, business white papers, medical reports, etc. Please take a look at my profile for more information regarding my qualifications, experience, and reviews. Would like to discuss details. Thanks. Mary
