Full API integration of affiliate e-commerce stores (windows .Net) + Interface + Scraping

To develop store with back end in .NET with amazon and ebay and aliexpress and another 15 API FULL/ENTIRE integration plus scraping of other sites which doesn't have affiliation program. Full setup and integration! Front and back end I would like to put together asap online store where I will use Amazon, EBay, Aliexpress and 15 other similar stores APIs to have affiliate program running from them (not scraping) and then to include products from staring with 40 stores – this will be products scraping which will be then put in the database (.net) this database will have to be updated once/twice a week. Store will have of course Buy option for all the products, will be available in multiple languages and different currencies, interface will be simple. General scraping: • Avoid duplication of the products, just pick the best price once to display in the search • Suppliers: select only top rated suppliers with 4-5 start rating • To display only the products that are in stock • Front end automatically showing the lowest price result to highest • Not to include ANY parts – computer, automotive, bikes, etc etc – no parts to be shown on the results (to avoid when the buyer is searching for bike for example he gets bike parts) 4
