Need help crafting an offer for Jamaal Charles

[RobMonge]

10 team league, PPR. This is my current roster:

QB Matt Schaub, Hou QB
RB Ray Rice, Bal RB
RB Felix Jones, Dal RB
FLEX Kenny Britt, Ten WR
WR Larry Fitzgerald, Ari WR
WR Hakeem Nicks, NYG WR
TE Jimmy Graham, NO TE
D/ST Lions D/ST D/ST
K Sebastian Janikowski, Oak K
Bench LeGarrette Blount, TB RB
Bench Julio Jones, Atl WR
Bench Davone Bess, Mia WR
Bench Danny Amendola*, StL WR
Bench Deion Branch, NE WR
Bench Ryan Fitzpatrick, Buf QB
Bench Aaron Hernandez, NE TE

The guy who has Jamaal Charles is in desperate need of WRs and I think I can leverage that pretty well. Should I try to get Charles from him or would it just be best to stand pat at this point? I was thinking something like Nicks plus Blount or F. Jones. What's a good starting point for an offer and what should be the most I'd be willing to part with? Thanks in advance for the help.

His roster, for reference:

QB Drew Brees, NO QB
RB Jamaal Charles, KC RB
RB Peyton Hillis, Cle RB
FLEX DeAngelo Williams, Car RB
WR Marques Colston*, NO WR
WR Steve Johnson, Buf WR
TE Owen Daniels, Hou TE
D/ST Steelers D/ST D/ST
K Rob Bironas, Ten K
Bench Malcom Floyd, SD WR
Bench A.J. Green, Cin WR
Bench Brandon Jacobs, NYG RB
Bench Ryan Torain, Wsh RB
Bench Thomas Jones, KC RB
Bench Mark Sanchez, NYJ QB
Bench Donovan McNabb, Min QB

Yeah I'd say either Nicks or Britt and Felix Jones or Julio Jones for Charles sounds good to me. Only reason I'd say Britt is because I don't know if I helieve in his QB. Charles is a definite pick up and will have a great year (he was my #1 draft pick)
