What WR should I trade for?

I am in a 12 team league on cbs... winner wins about $600... I'm stuck though... I drafted TO and he has been a huge disappointment... I need to find a number 2 WR... These are my WR's right now... Roddy White, TO, Hester, Lance Moore, Breaston, Caldwell... I need to know some WR's to look for and who i should trade for them that would be a fair trade... So this is my team... I need a number 2 WR to have a chance at the championship... I'm sittin at 3-3 right now... Some guy has Chris Johnson and Brian Westbrook on the trading block but I feel I need a WR more... So help me out guys

QB - Romo, Garrard
RB - LT, Rice, Julius Jones, Jonathan Stewart
WR's Already named
TE - Carlson, Finley
K - Folk
DEF - Packers

if you can, go for calvin johnson he will put up a huge amount of fantasy points trust me.
