Coins price comparison Price Engine

I need a coder to develop a coin price comparison search engine. I need to take current coin auction listings as well as current inventory from [login to view URL] and compare with [login to view URL] FMV fair Market Value against current auction listings on HA.com. Then to generate and rank in order by percentage below numismedia FMV the current inventory of available coins at [login to view URL] I need the following date fields: 1.) Date of the coin "1877" 2.) Type of coin denominaton: 1c, 5c, 10c, 25c, 50c, $1.00, $2.5, $5.00, $10.00, $20.00 3.) Coin Grading Service: "PCGS" [login to view URL] "Professional coin grading service" Only 4.) Grade or Condition of the coin (1-70) Example: G6 is (good 6) F12 (Fine 12) AU58 (almost uncirculated 58) MS63 (Mint State 63) 5.) Negative info. Negative fields to not include in the search: Example Corroded, cleaned, filled rim. 6.) Positive Info to include in search: blast white,un-toned, no spots, CAC certified. 7.) Links to Numismatic Web Sites: [login to view URL] [login to view URL] www.teletrade.com. I want to start with [login to view URL] as Heritage Online Auctions has the largest inventory of coins to purchase. I can explain in more detail to a coder to clarify any questions and give examples of coins that I purchased and why. I currently spend way too much time to find coins suitable for purchase and this will be well worth paying to find a solution. Regards, Brian
