I would point you towards the "Unofficial Friendly Steam Trading Thread" [http://www.escapistmagazine.com/forums/read/9.408230-The-Unofficial-Friendly-Steam-Trading-Thread]
Also, posting the product code, and a thread with such a title, kinda doesn't work so well. I'd go with "First person to message me gets it" in the future.
