Help me put together a trade to strengthen RB.

WHIR!

I am in a 0.5ppr league and we start QB, RB, RB, WR, WR, W/R, TE, K, 5 IDP
We have a limit of 2 QBs, 4 WRs and 4 RBs total on the roster.

My WR core is good, but I'd like to make a deal with someone to strengthen my RB position and get a solid RB2.

Please look through the rosters before and suggest a good RB2 I should target, and ideally, which of my WRs I should package to get another back. Ideally I would like to package Miles Austin in order to keep Calvin Johnson.

Here is my roster from this week (I won, now sitting at 2-4):
QB- Freeman
RB- Gore
RB- Carter
WR- Calvin Johnson
WR- Austin
W/R- Moss
TE- Ben Watson
K- Janikowski
5 IDP players
Bench- Tebow
Bench- Tomlinson
Bench- Redman
Bench- Holmes
Bench- Keller
Bench- Marcedes Lewis

Here are the rosters of a few other people with decent RBs or who have weak WR spots who I'd like to make a trade with:

Team 1:
QB- Tom Brady, Jay Cutler
RB- Matt Forte, Mendenhall, Shonn Greene, Tolbert
WR- Desean Jackson, Steve Johnson, Meachem, Moore
TE- Finley, Hernandez

Team 2:
QB- Ryan, Flacco
RB- McFadden, Starks, Steven Jackson, Addai
WR- Wayne, Bess, Williams (TB), Burleson
TE- Pettigrew, Miller

Team 3:
QB- Sanchez, Painter
RB- Bradshaw, Best, Chris Johnson, Wells
WR- Maclin, Garcon, Burress, Ward
TE- Davis

Team 4:
QB- Vick, E.Manning
RB- Fred Jackson, Benson, Hightower, Tate
WR- Jennings, Nicks, Heyward-Bey, Mike Thomas
TE- Witten, Boss

I've had teams 1 and 3 express interest in Calvin Johnson and Miles Austin. And Team 4 is looking for someone to take Eli Manning because of BYE week conflict next week, but I don't really want Eli.

anyone?

the only RB worth getting from Team 4 seems to be Fred Jackson, and I don't see him letting go of him.

I'm leaning towards trying to put together a deal to get either Bradshaw or Wells from Team 3 of Forte or Mendenhall from Team 1.

Which of the following RBs would be worth a straight up trade for Austin + maybe someone else:
Forte
Mendenhall
Bradshaw
Wells
McFadden
Steven Jackson

I'm thinking Mendenhall, Bradshaw or Steven Jackson?

Only thing about Bradshaw is that he is on BYE next week, and so is Gore. So I'd have to play with some scrubs for week 7, although I am up against an 0-6 team.
