Realistically it's three days work with prep, moving in and out, cooking and cleanup. So what would you expect to earn for three days work?
I wouldn't let them get the meat because it's unlikely they'll get exactly what you want and when you want it. Typically people do that because they're looking to save money. I'd offer the meat at cost but charge three days pay. I doubt they'll pay it.
