I'm a new lecturer at a university in Bangkok and sometimes get requests for proof reading and private lessons for IELTS and once for English classes for a small international company. I have no idea what is a fair price. Rather than post separate threads for each situation, I'm putting them together in one post. I would really appreciate your suggestions since most of the information I found online is outdated or doesn't fit my situation: 1) how much to charge per word for proof reading a thesis/academic paper for a graduate student/ teacher? One time I charged .6 baht per word (1200 baht for 2000 word article) and not sure if I'm under selling myself because it was very time consuming to edit the grammar for almost EVERY sentence. BTW I have a background in academia, but I'm not editing for content. Just for grammar, readability, formatting, etc. 2) how much to charge per hour for teaching business English classes for an international company? I imagine 2 to 3 hours per week. I would supply whatever materials needed. A Japanese/Thai business approached me to teach English classes, but I'm not sure what to ask for. Thanks again for your suggestions. Cheers!
