data scraping from amazon product category(watches)

Hi, I have a prestashop site, and i want products from amazon (watches category only) scrapped and inserted into my site. Around 420 000 products i think, but not sure. we need title, photos, descriptions, caracteristics, ASIN, EAN/UPC, brand name, category name etc etc. We will modify all data on excel , and load it on a new prestashop. we will not upload products manually of course, you will have to right a script that will insert data in prestashop database. Please bid for the complete process that is mentioned above. Happy bidding Thanks
