Are you looking for a local proofreader? If so, I suggest your local press. If you don't mind where the person is, ask your friends and colleagues who have used such services or Google it and then carefully read the testimonials. It might depend what you need proofread - if it's a technical document, you'll need a specialist service.
Please look at my corrections to your post above in red. You have given your native language as English and said that you are an English teacher. As such, it is vitally important that you use correctly written English on this forum (and everywhere else). The learners on this site will assume that everything you write is correct when they see your member profile.
