Custom eBay/Craigslist Search Program

We need a programmer who can create a custom program for our own use which consists of two important components.  1. The program must be capable of searching eBay COMPLETED auctions and returning the most CURRENT results which meet our criteria. For example, the results must contain results with multiple bidders and where the auction was completed successfully.  2. The second piece of them program must then search all of Craigslist to find the same items, but at a reduced price.   3. The program needs to run continuously without user intervention. For example: On eBay:  1965 Fender Stratocaster  Sold for $11,950 32 bids / 18 bidders Search all of CRAIGSLIST for: 1965 Fender Stratocaster Price $6,000 OR LESS   Please Note: we need to be able to set certain criteria for the eBay search, such as maximum price. We are ready to start today. You must have at least 10 feedback to bid..
