We'd like to lauchn a business website in France which ennables companies to find suppliers.

The site would be made of two parts: one for the companies (with a posting area) and one for the suppliers (with subscription forms, accounts where to deal with their projects, etc.) The structure and the functionnalities (validation processes, project management, etc.) might be very close of this website's:

Budget: $ 750-1500
But might be higher with good referencies in your portfolio
