the only elk hunting guide I've used I wouldn't again, they were great for a vacation just not many elk.
One recommendation would be a booking agent. they have access to LOTS of outfitters and can give you lots of options. There are many good ones around, a friend of mine uses
www.hunts.net and loves them
One of the reasons people are asking for more info is that the price range will vary GREATLY, you can get a public land 5 day hunt for a couple thousand up to the Cadillac outfitter where if you are asking the price you can't afford it, but will get a monster.
If I were elk hunting, one place I would seriously consider (but you need points) is triple3 in Wyoming.
