amazon bestsellers

I need a script that would pull out [login to view URL] best selling 100,000 (10,000, etc. as designated) products in designated category. The information that needs to be pulled out: 1. Sales rank 2. Name of the product 3. UPC/ISBN number 4. Author/Maker 5. Thumbnail This script can be build on any website platform (Joomla, Wordpress, etc.) The script has to be open/susceptible to more modifications in the future as I will need to add more functionalities.
