permit to sell carcasses

Are there requirements for selling legally taken frozen raccoon or coyote carcases?

Disability prevents me from skinning my dog-caught raccoons. I usually freeze 'em, then give them to a trapper in my area who gives me a few dollars to help with gas and dogfood. The guys I generally use decided not to trap this year and the alternate died. Others I've spoken to only want 'em free. Thought I might offer 'em via Craigslist, but don't want to get in a jackpot. Do I or they require "Fur Buyer's License", ect., or is my Hunting license sufficient? Do I need to varify their's?
