Fifa 12 Ultimate Team Autobuyer

Hi there. I am after a Freelancer who could write a script and build a software for a Fifa 12 Autobuyer. The autobuyer must be able to buy players, that you have entered using either a list of players or a search bar, and will buy every player that is on the market under a set price (which the user can set himself). It must refresh quickly so that the market will be up to date. the items to search for can be players, consumables or other items that are for sale on the ultimate team web app. also if possible the software should have an easy to use user-interface. Im sure you know the drill with this as many have done this before and I am hoping one of you good people have. Thanks.
