Dear Sir,
I receive your invitation to place a bid on this project, and so I am here. As I don't know the total words of your project, I would provide a rate of 0.025USD/source word unit price for your reference. Basically, I can translate 2500 English words or 3000~3500 Chinese words every day, so you can estimate the date of completion.
I am a freelance Chinese – English Translator & Interpreter with more than 6 years experience, Bachelor of Economics, Shanghai University. Thank you for your invitation and hope my rate and qualification can satisfy you.
Sincerely,
Chris
