If you can't afford a custom bow, check out some of the old Bear Grizzly or Kodiak magnums. Short, quick, quiet, and my Grizzly is about 56" when strung and I'm about a 27" draw. It's made for a 28" draw and I can pull it back at least that far with no problems, but I'm just more comfortable somewhere between 26" and 27". I shoot 2 under so I probably don't notice any finger pinch like some who shoot 1 over 2 under would.
I believe the Kodiak magnum is even shorter tip to tip and was considered a "Bush Bow" by some of the older generations. I wish I had one.
