Amazon Price Tracker - PHP and Amazon Web Services(repost)

I need some existing PHP code modified. Here is the application now: <[login to view URL]> I need the program modified so that it will display the prices of several hundred products on Amazon being sold by 3rd party marketplace sellers - not just one product. I will need the program to read several hundred ASINs that have been hard coded or provided via text file. I also need to be able to cap specific items by price (e.g. do not display ASIN xxxxxx if price is greater than $50) . So perhaps the input list would be something like this: ASIN, Cap (“X?? or something would need to indicate no cap): 123456789, 50 111112222, X 222223333, 100 Show items in "good" condition or better (do not show any listings in "acceptable" condition) I also would like a drop down box with the option to only display items being sold by a specific seller or to view all sellers. I will also need to be able edit this list of sellers. I will provide you with the existing code and an initial sample list of ASINs and sellers to be used. Summary: 1) Remove the "Find a merchant selling a product with ASIN:" 2) Add a mechanism that reads a stored list of ASINs and price caps (again, list is not entered by hand - it's coded within the program or read from a file) 3) Remove the "condition" drop down portion 4) Modify the "states" portion to "sellers" 5) Once the selection has been made and submitted, the resulting pages should display the products priced lowest to highest, with only the following fields displayed on the webpages: price name of the product condition condition notes seller name a URL to the listing (please substitute the actual URL with “click here?? or something like that using ) ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
