I can't imagine you would need a guide to take an antelope unless you are looking for record book type buck. CO, ID, WY are probably the easiest to get a tag in, CO and WY are almost a guaranteed doe tag. With a rifle, antelope hunting is not much of a challenge if you are meat hunting. I myself look at it as a nice weekend off from intense hunting. This year literally we did no scouting, the first spot we went at daybreak there where several hunters so we moved, second place same story. Third place spotted about 20, 30-minute stalk to get within 700 yards, range, dope, shoot, hunt over, back at truck with meat by 10am.
