Amazon UK Page Ranking Data Extraction

We are looking for an experienced programmer to write a simple bot or simple extraction tool that extracts book data from the Amazon UK website. The program needs to extract full book data into a database file, including title, author, description, ISBN and most importantly [login to view URL] Sales Rank when given specific search criteria, such as book publisher, author etc. For example a search on the publisher Headline Publishing Group would produce about 2000 results at 12 to a page, or about 180 pages. From this search we would require the data listed above for all 2000 items placed in a database or spreadsheet file. The object is for us to be able to analyze which books have the highest ranking from any given publisher, across the publishers entire list of titles.
