Thanks for responses. Why asp and mssql? cuz I think the business model is more critical than technical concerns for success of a startup. So maybe it would be a good choice if we could build the model as fast as posssible at low cost and test the model in real world before we move on. Now Im working on this site: www.doumart.com. Shot me an email if u r intrested.
BTW, im also looking for partners in business information service, media, and industry research (www.quant-media.com).
