Online book store with Zen-Cart - interface with Amazon.com

Looking to have a back end application linked to Zen Cart shopping cart and Amazon. Here is the break down of what we need: - Back end application must be able to query Amazon database and compare ISBN # that was scanned at local computer and compare with Amazon. If ISBN'S match then program looks for a photo of the book in Amazons DB. If the photo exists then a few things occur: Application will: 1: Copy down - Photo of Book,Publisher,Any dates relating to the book, List Price and 3 highest prices and 3 lowest prices if available 2: Once data is transfered it will be placed in corresponding tables/fields in MySQL DB and will be visible in Zen shopping cart. If possible process should be able to run in real time however if process is run as a batch then that is ok as well. I need someone who is very knowledgable with linking to Amazons database and querying it. Also we need the following: - Each product page (meaning each page that 1 individual book appears on) should be SEO optimized for indexing. - Each product page should have a place for placing Google Adsense ads and room for banners on the botton and top of page - A google/yahoo sitemap in XML should also be created for this project and delivered to us - WE will submit to Google and Yahoo. - You should create a very elegant yet effecitive front page, contact page and product pages for this site. All adhering to SEO and standards set forth above. Again if your a pro at connecting to Amazon and can deliver this project at 500 dollars and interface with Amazon, Zencart do it. Then please place a bid. Thanks
