save your money and dont hire an outfitter. antelope are plentiful here in wyoming, and im sure the other states ya mentioned are similar. maybe find a landowner and even pay a small trespass fee if necessary, but i "guide" a lot of swap hunters that i take, and we are 100% every year, on public land. 13 inch plus goats are the norm, which isnt huge, but certainly very nice, and make a great mount. thats just my thoughts on it, but i really dont think ya need an outfitter.
