Where you are is going to affect the licence cost.
Non-resident licences, if they apply, are expensive. Montana for example wants $1,250.00 for a licence. $2,256 for a bull, $1,756 for a cow, both non-trophy animals(that's $5,000, but residents only), in SD. And there are rules about the bow as well. All for a One Day hunt. Mind you, it's in Custer State Park. Appears to be there only.
North Dakota doesn't mention Bison on their Game and Fish Department site. Contact these guys for info though.

Figure on about 300ish pounds of meat that you get to transport.
Saw an RCMP buffalo coat in a shop years and years ago. Guy told me it weighed 60 pounds.
Bison meat is extremely lean stuff. Tasty though.
Like buck460XVR says, figure out your budget first.
