To quote Chief Bodie: "You're gonna need a bigger boat".
If you are serving 1/4 pound of each to 400-500 people you'll need about:
200# raw of each meat. The yield on chuck and pork but is only about 60%
This would provide approximately 480 1/4/ pound servings of each meat.
I'd charge at least $8.00 per pound delivered.
So, 240# x 8 = $1920.00
You can certainly do it cheaper, but you are going to work your tail off.
