I developed www.salesmoto.com, reverse-auctioning for enterprise technology purchasing. Buyers open up proposal, vendors join the network to provide a quality pitch.

I built Salesmoto to focus on technology services and quality consultation by vendors rather than focusing on products and quotations. - because services at the end is a B2B partnership, and cheapest is not necessarily the best. I also want to dedicate to introducing enterprise buyers (or SMB buyers) to alternatives and new enterprise startups.

Upon research, its a chicken and egg problem. Get buyers first or sellers first. This is a very excellent article analyzing how to build ANY marketplace: http://blog.asmartbear.com/marketplace-business-model.html - Jason recommends getting sellers first

How do I ensure building a proper enterprise buy / sales marketplace? - Business-model, user repeatability, value-added

What are some unorthodox ways or approaches you guys can recommend from past experiences to get the ball rolling?

Thanks, Gary
