Auction Tool in Russian

I am looking to develop an application which can be used by buyers of large cooperations to conduct online auctions with suppliers. The way it would work is that a buyer would log into a hosted application, send invitations via email to suppliers who then via a link or url would respond to the inviation to participate in an auctions. The auction is at a predetermined time and date. Suppliers will be able to compete in the auction and teh buyer as well as the suppliers will be able to see eachothers bids but not who is bidding. The buyer will have transparency and will be able to see all information. Upon expiration of the auction, the winner will be announced and a summary of the award will be sent to the supplier. Each supplier will receive a notification with a summary of their quotes and how much it deviated from the winner. I am open to suggestions. regards Robert Dammerman
