I currently have a Python script for a Fifa 13 Autobuyer.
An autobuyer is something that connects to the EA servers and searches for players and buys that player instantly if that player is put up for the price specified or below. It then lists this player up for auction instantly.
I have a Python script for the autobuyer, and all you have to do is change a few things so that it searches for a player instead of a contract.
Contact me for more information.
