Need head start/ideas for a new application using the portal

Hi,

I am just looking for ideas, or direction, about a new app.

Simply put, I have multiple vendors offering products, and multiple customers buying those products. BUT the administrator controls the product offering and prices.

For example, Vendor "A" offers 20 lettuces and 30 brocolis. Vendor "B" offers only 35 brocolis. Customer will see that lettuces and brocolis are available. When he chooses to buy brocolis, he sees that vendor "A" has 30, and vendor "B" has 35, both at the same price fixed by the administrator. If he buys from vendor "A", the quantity offered by this vendor will be reduced accordingly.

It is kind of a multiple werehouses with same type of products and prices. How would you go about it ?
