Amazon to Shopify App. Shopify App Development. Scrapers

Ok Guys, If you cannot develop a shopify app or does not know the shopify api's then do not bid. If you do not know the Amazon MWS API do not bid. Please read this carefully to make sure you will be able to do this job. I want to have an app/software/scraper that scrape amazon products from their ASIN or URL, then post this to Shopify and then Monitor the Inventory and the Price. So here is an outline of what it should do : So I want to open the software, Paste my amazon links or asins that I want, then this should grab from amazon add my percentage that is a variable increase formula to the amazon price and post the product to shopify, this now include the images the titel the product features the product description and the stock. This must then be monitored if the stock or price change on amazon the software must reprice and update the price on the shopify store. If you look at the following link : [login to view URL] This is almost exactly the type of app that I need, the only difference is that it should use AMAZON and not ALIEXPRESS. The functionality stay's the same. Give me more information regarding your experience with Shopify API's etc as well as Amazon.
