Fifa 13 Ultimate Team Autobuyer revision

Hello, I currently own an Autobuyer for Fifa 12 on the Xbox 360 that was designed by you. On September 25, Fifa 13 will be released in North America and I will need a new Autobuyer before then. I would like it to be very similar to the old design but with a few key changes. The changes are as follows: 1. When an item in my trade pile expires, I do NOT want it to be re-listed automatically 2. I would like the new Autobuyer to be faster and more efficient if possible. The one I currently have often misses players which results in lower profits for me. Also once it finds a player it takes about 4-5 seconds to purchase the player and I would like that time reduced. 3. Lastly, the Autobuyer I currently have randomly shuts off or stops working after varying lengths of time. I would like for that to NOT happen If you can make these 3 key changes I will be very happy. Please let me know how much you think this will cost, as I am willing to pay you a handsome fee if you can apply the changes which I have requested
