Amazon.co.uk / eBay arbitrage software (WEB based or Desktop APP)

I need a software coded that will do the same things as [login to view URL] and [login to view URL] if i have to give more details it would be; 1) you enter a ebay seller username, and it goes to their store and scrapes all their listing titles, after that, it copies those and checks those titles in amazon, and tries to match products (with the exact title) and shows the price difference between them. after that you can save it as a CSV file. 2) listing creation, you enter the amazon ASIN and it will create ebay store listings, using an HTML template that we have created, (it will fill details from amazon into this listing). like title, pictures, and descriptions. (the pictures will be saved onto the server). 3) every hour or two, a cronjob will run and check the price on amazon, and if the price is different, it will adjust the price on ebay, by revising the item. the software needs to be able to change price based on factors (like a fixed/percentage profit and minimum profit settings.) (like %20 percent profit, but make at least 5 GBP profit.) It also has to check stock levels with amazon and update this.
