Amazon Data Fetcher

Need a software which can work to fetch data from Amazon website URL. We have doing it through one small software putting up URL (amazon URL) and getting data in CSV files. It can fetch single URL or fetch CSV file with mutiple URLs with filenames and then saves each URL data as CSV with given filename. We have more than 400 URLs with about 5000-6000 ASINs in URL link. So about 2 million products An example of URL is - http://www.amazon.com/s/ref=sr_nr_n_2?rh=n%3A165796011%2Cp_85%3A2470955011%2Cn%3A%21165797011%2Cn%3A166736011&bbn=165797011&ie=UTF8&qid=1410205879&rnid=165797011 This link shows 4740 items in 198 pages, 24 products each page. So software should be able to fetch required data from all pages in this URL. We are looking for is: 1. We can fetch List Price, Price, ASIN of each product 2. It fetches Data as fast as possible and saves as CSV files. Our old software could fetch all this data in 3-4 days 3. It can fetch single URL or multiple URLs at one time saving multiple CSV files. (We provide link to csv with mutilple URLs) 4. We can open this software multiple times to run many URLs or CSVs We would first test it and then make payment. Earlier we have paid and got scraps only.
