I need to create a reverse auction program. The "clients" will post jobs. The "bidders" will bid on the work both with live bids and automatic bids (in their set up). The clients will post the job, but only a part of the job will be visible at auction time (type of job, state and county). After the winner wins the bid, then the rest of the job is emailed to the winning bidder. Both client and bidders can not know who each other are so user names need to be created for each. In order for the auction to be competed, the bidder must be able to return documents to the client via a fax server. If possible, the bidders will have to pay a monthly fee to be a part of the auction and the monthly fee will be based on how much area the bidder covers. Payments from client to bidder will have to be done via an escrow account or service.
