where do you live? and how much work do you want to put into it? some possible options based on your answers to the above are:
talk to a grocery store that butchers, or at least breaks down primal cuts.
find a custom slaughterhouse (the guys that do the butchering for all those buy a side at farmer's market dudes).
buy a sheep/goat/calf (dairly calves are often almost free). take it behind the shed with your rifle hidden behind your back, cut up and stick in freezer, ???, profit.
buy a cheap hunting license, shoot free female deer, cut up and stick in freezer, ???, profit.
