Ok well basically a coworker has asked me to cook some BBQ for her daughter's bday party. She has asked me to cook 2 butts about 10-12lbs in size for some pulled pork and 6 racks of BBs. I am not buying the meat either which is a no no for allot of you but I had said I picked up all of my stuff at BJs and she is also a member so she said she would pick it up. Other than that I am not cooking or supplying anything. My simple question what is a fair price to charge for cooking this BBq for her? She is supplying everything but the Rub, Fuel, and Smoke Wood. She estimates that there will be approximately 18 adults and since its 12yr olds bday a bunch of young adults.
