You can find some one from here from this page ,than you can confirm it before you come.....

First choice you can try to get touch with your friend in China whether they can recommend some one to you,
If no suitable, you can try to search the translator company in China by internet or professional translator Web, As far as I know, it is not so cheaper to get a translator from there. Of course, there is a lot of translator information from this forum.. I think there is no harm in try..
First feeling and communication will let you know who is the best suitable for you..
