I suggest going to another shop because those bozo's are out to gouge you. I've got a 33 1/2" draw and have never had to pay extra for a special order bow. Of course, I've never been able to buy a compound off the rack after being able to shoot it, and I've wound up with some real stinkers as a result. But talk about a narrow selection!
Any pro shop worthy of the name will have at least a few bows in 31" draw on hand. Slap a 1/2" string loop on it, adjust length of pull on the release and there you go. There is also some adjustment of string and cable lengths that can easily change draw length by a half inch. No sweat.
I hate to start recommending bows, because invariably you leave out somebody's favorite. I reckon they can chime in and fill in the gaps though. You can't go wrong with any of the more popular name brands like Hoyt, Mathews and BowTech. Some of Martin's offerings I don't care for but their Scepter and Cougar elite models are nice.
Good luck! But, unfortunately, I must inform you that you do not qualify to join the Ape Arm Knuckle Draggers Association. Pinky might though...
