I need to know about how many sandwichs a 9lb butt will make if I use regular sized hambuger buns. Please don't laugh and don't tell me "It depends on how big you make em". Here's the rest of the story: My wife and I have a concession trailer we operate in the warmer weather. Recently I fixed some pulled pork and had another couple over. He owns a large mfg plant with about 300 employees. He really enjoyed my pulled pork and after dinner ask me if we would be interested in sitting up in his parking lot on Mon/Wed/Fri and selling sandwichs. He said they have nothing but ratty old vending machines in their break room and is sure we could serve at least 100 people a day. We are already set up to sell hot dogs, chili dogs, nachos, and drinks at local craft fairs and shows. I can smoke 6 butts at a time in my 2 GOSM's and I figured we could smoke them, pull them, put on the finishing sauce, vacum seal them in 1 gallon pkgs and freeze them. Then put them in the roaster oven we have in the trailer, warm them up and serve them as needed. My very serious question is, how many butts would I need to fix 300 sandwichs a week. I can easily get $4.00 each out of them but I need to know how many sandwichs I could get out of 9lbs to figure my food cost. I think we could make some decent $$$ but I'm trying to get the plans worked out in advance. I need some help and ideas on this before I commit to him. Mike S.
