I am Chinese from HK, I speak both Chinese and English fluently. Currently I am working in an American investment bank. I have translation experience in my previous jobs. I saw few bids above are quite funny to me. It seems these people hadn't got what you actually wante. Many of them sound like native speakers of Chinese more than English. I think English level of the ad you post is much better than these bid. If you waste your time to search a right candidate in these bid, why don't you do the translation by yourself, or consider me. We can discuss in phone if need.
