If you have a local butcher shop (ee gads, I'm showing my age!!) ask if you can purchase some from them, or if they would sell you a roll or whatever. In the old days, they would just give you a hunk of you were a customer..can we say small town??? Do you have a fairly local resturant supply? Or a friend that owns or works in a resturant? Its out there, keep searching. Good luck.
