My colleague and I are planning to start up a b2b site providing imp&exp trade leads, a trading infomation platform something like Alibaba. We have studied Alibaba and seems most of the income they generate comes from the supplier side. It's kind of difficult at the moment to generate any new ideas -which means we might have to follow what other market players are doing now. Can anyone here give us some suggestions on the business model, or any recommendations of other similar websites which we can study, or anyone who have dealt with those kind of websites can give us some kind advice.

Many thanks for your kind help.
