Buying Steam account with Cod 4

I will give you a steam account with half life 2, half life 2 episode one, half life 2 episode two, portal, and team fortress 2 in return. TF2 multiplayer works perfectly. I will even throw in a battlefield 2 serial key

Call of duty 4 account must have single player and multiplayer working 100%

I have a Steam account with COD4 with many other games.
So this ain't worth it.
I also got BFBC2 and TF2 already. :P

uhh is Cod4 The one with multiplayer and the crappy single player cause the key is sharable
