We call up the rancher / farmer and buy the whole cow then a custom slaughter house / butcher get it and cuts it up. You probably want it hung for 30 days in cold storage. People do this, a co-worker goes out to Montana each year. Some grocery stores in the area do this, it's cheaper than buying the individual pieces.

You can buy a cow and have someone kill it and butcher it. I've known people that have done this.
