Amazon Product scraper

I need someone to create a script/desktop application for me which scraps best sellers from each category of amazon. the script must take advantage of amazon API. the script should also be able to scrape data of given products (based on ASIN). the scraped result must be saved in a csv file. all details are needed to be scraped. data required (title,description,technical details,dimensions,ASIN,Model number, UPC(if available)) if possible the script should also download all the images of each product and put them in separate folder (named after the product name) into main amazon folder.
