Question about charging for cooking

[bbqwilly]

Im cooking a bunch meat for a buddies Memorial Day party. He bought the meat and I am cooking it for free. He says that there is potential to get some business from some of the guys at the party to cook for other events.
My question is how do you charge when you cook meat for others?

This is a better question for the catering section.... Be prepared to get chewed out for not being a legit catering business...

Thanks for the heads up. I should have asked it over there.
