If the local high school has a Future Farmers of America (FFA) program, they can help or point you to a local meat packager. The local meat packager can arrange the sale of a beef, pig, goat, lamb or whatever is available. Very nice.
Down side is you get everything. Some people don't care for trotters, tripe or the like. It does make good healthy dog food. Ask around, you might be surprised who is familiar or can help you in this area.
I have chickens, process venison and have connections to farms. Life is good and it tastes so much better.
