www.alibaba.com have you tried that? there are many manufacturers on that site from china.
Anyway Good luck
Minimums of 12 t shirts and have wholesale customer programs. The website is mostly informational, you'll want to give them a call or email to discuss what you want, but they print for brokers, designers and other printers and embroiderers. Compared to the big internet only based screen printers, their prices are good too!
