yeehaw.... lets just help the feller////
heres my nickel.....
everybodys cost and yeilds are different. even from batch to batch. what i suggest is take your worst case scenario and do your math that way. i like to calculate in the price of making all that 'q'. for me, it aint cheap. i use wood and gas and electricity. plus regular bbq supplies and 'software'. so.... i figure my cost at 3.00 per pound. if i am way over, good for me.
next step is, if there is a place down the road that sells bbq sandwiches, you gotta either be competitive, or offer something 'off the chain'.
and the most important part..the size; well, that depends on how much you want to move. lets say you sell 10 sandwiches for lunch. do you want to sell 2.99 1/3lb sandwiches or 4.99 1/2lb sandwiches? well, lets do the math... done.
conclusion? the more you move, the more you make.
heck, i would sell a 2 pound sandwich if someone would buy it.. the more you move, the more you make.....simple
