Amazon/Ebay comparison site - repost

the webpage: [login to view URL] I have an Amazon & Ebay price comparison site for Spain, and need some fine-tuning for the website This should only take a few hours to complete (skills required would be good knowledge of Amazon/Ebay Api integration, PHP,javascript) 1. Dropdown lists When a dropdown list is selected, I need all text/results/URL on the page to change dynamically (ajax style). Also need to add a sort order option for both columns (the default should be ascending) 2. Amazon API  I am registered with Amazon sites in Europe (UK,France,Germany etc), and need the search results from all these sites to appear on this page (showing which country the product comes from, and the the total price to Spain, including shipping cost) [login to view URL] categories I need to consolidate both Amazon and Ebay subcategories from the results, and show them in the "Filter" column on the website (with counts)? The results from both amazon and ebay can then be refined from these categories (and subcategories of subcategories). 4. Pagination Need pagination & totals from both Amazon and Ebay results, and for them to be dynamically updated when a dropdown or sub-category is selected.
