I have an old chest freezer that I will throw a deer in, or elk quarters, to keep them cold. Usually I end up letting it run overnight, then I'll unplug it during the day while I go to work, because I don't want the meat frozen solid. If I'm not working (or hunting) I'll be cutting and wrapping that day. It's a bit of a hassle trying to keep the temperature just right so the meat doesn't freeze, but it works for me. It beats paying to have it done and then not even knowing if you're getting the right meat back.
