You will have a contract with that company not the school they will send you to. And they will deduct a certain amount each month from your salary. Forget them!

I did a summer camp for this outfit once, and while I was paid in full, it did seem very shifty and all about profits.

Try for a uni job in China. chinatefl.com lists many uni's and it is free to use - just contact the uni directly

Are you sure they are not a recruiter...I maybe know more than you do on this fact!
