Please understand, we collectors can't begin to guess what you have, therefore we have no clue what to say to you.
How many ForgeWorld creatures do you have?
I'd suggest talking with @pretre. He helps move miniatures and I venture he can help you get top dollar for them.
Please realize w/out details it's going to be really hard to get anyone to speak up, simply out of the fact the world's your oyster and they don't know where to start or shuck which end.
(Not sure that works, but toooo bad)
