Chad, I'll be getting 8-9 lb average butts, but this is a once-a-year gig... Up to 400,000 people if the weather is good, coming to a town of 2500 for a weekend.
I was being conservative, guessing 800 sandwiches per 50 butts. The good part of being conservative is that, if there's more, it will either sell, or the guy we're working with will buy it and freeze it to sell later. He wants to talk after this about doing a once-a-month pulled pork day... I'm all for it!
I bought several gallon jugs and pumps to fit on them, to have 3 pumps at a time, one for 3 different sauces. We're going to start cooking on the 12th, overnight, doing 50 butts, then pulling and storing while 50 more go on Friday, then again Friday night if the weather's going to be good. So we will potentially be cooking about 1200 lbs of butts for a weekend!
Good advice on the weighing of the cases. We thought about getting cheaper pork, but we're getting a good price on Premium Standard Farms, which seems to be top quality pork. We're going for quality as well as quantity.
The bad part is that, because of it being a festival, the guy we're working with is being careful about how we're doing this (that's not the bad part). He wants to not say anything about us doing the pork; we're just working for him, in effect, for the weekend. The cash we'll make allows me to not care.
And the once-a-month gigs will be done advertising that we're doing it. He's a local, and he's more than willing to help us out in the long run.
