Counter Strike / Steam trade bot key and items

i need a bot to trade for me. I need it to have a simple user interface. I trade keys for items in counter strike via steam. i need the bot to recognize how many keys are in the trade and what item i need to be able to set the price for any item i want to buy and or sell. I need to be able to add and remove any item it is buying or selling with easily. It needs to be able to trade keys for items and vice versa. i need to be able to set what trades to accept and what not to. I need the interface to be easy to use and for windows if any one can make this happen for a decent price let me know.
