Space Marine Bits

I have decided to build a space wolf razorback-spam list, and I'd like some bits 'n' kits if anyone has any.

I am looking for:

-3 flamers
-a space marine missile launcher
-4 meltaguns

Now, for those of you that have Rhino kits, I am interested in the little Razorback top hatch that comes with the rhino (but you don't get the guns, what the duck? oh well)

Trade or cash is fine, probably around $1-2 per bit. I have literally a billion tyranid bits, some Necron stuff, and of course some leftover space marine parts.
