We have a place in town that butchers meat and sells it. They call themselves a meat locker. We had the same problem. This meat locker had freezer drawers they rented by the month. It was like 15.00 for 4 cu ft.
Glad you got it all squeezed in.
Another thing if it wasn't done already - vacuum seal the meat, lasts longer and will really squish it into a smaller amount of space.
