Not sure if you can do this where you live or not, but here in MN the meat processors send all of their scraps to the renderer. They do not get paid for the material, and the processor takes all of their hides. The processors don't like the arrangement but they are over a barrel. They give me all of the scraps and bones I can carry, for free. I get a lot of beef bones that way, and also deer during hunting season. If I had room in my freezer I could fill it with deer heads- the dogs love them.
