Sorry it's not easy for me to write in Chinese here.
Here is my idea:
With enough people comes with enough purchasing power, this is especially true for people on this forum since most of you guys are running big or small companies in the US and/or China. A group buy site could be established easily and SEO optimized by lots of experts here. This group buy site will help owners, generate commission from general consumers, etc. There are a lot of group buy companies already in the US and are quite successful, it doesn't hurt to add one started and run by Chinese entrepreneurs in the U.S.
