Tough call. I get at least $8 per pound delivered for the pork. I "retail" ribs for $20 per slab but that's cutting my margin a bit. You're not doing enough volume to go totally "wholesale" on the guy. Figure your time and what you are worth and bill the time and materials you use.
A lot depends on what kind of cooker and how many hours you put it for prep, cooking, and pulling.
