Hmm.. I'm not 100% sure if this is what you want, but..

Guangzhou Sigma Technology Limited seems to be a company that sells bitcoin mining devices.

I don't think the company is solely for bitcoin mining though..

Here is the website where I found them http://www.alibaba.com/countrysearch/CN/bitcoin-miner.html
