Looking to trade some cards for CS:GO skins

Pretty much trading @ a 50% rate: $10 worth of cards for $20 worth of your steam wallet. And before anyone says something like steam wallet is cash, so why trade at 50%? Because the steam wallet is not cash. You can add money to your account but you cannot take money out, so selling a drop you got produces no real world value...until now! I am currently trading some cards for a CS:GO AWP skin, so I know there are some of you guys out there!

Looking for:
-StatTrak™ P90 | Cold Blooded
-StatTrak™ P250 | Hive
-StatTrak™ Glock-18 | Dragon Tattoo
-StatTrak™ AK-47 | Red Laminate
-And a reach: Any of the Knife skins. These range from $80-$125 (the ones I can afford )
