Large Ham with bone

I want to purchase a large ham with the bone similar to the ones you see at the Breeze Super that they are carving up and overcharging for. I think they sell them as well here in TienMu at some of the butchers, but I am looking for something more reasonably priced.

There is large supply of good quality domestic pork and companies like FuLong should produce these no? Where to purchase one at a reasonable price?
