I also only tend to do DIY hunts, unless legally I HAVE to hire a outfitter!
as for your question what would one expect for a 5 k elk hunt
IMO< they SHOULD be getting a very GOOD hunt, they should have access to lands(most at this price and UP should be on private lands too, or limited draw/access lands! at this price point IMO and lands should have a healthy population of ELK at the TIME of the hunt!
and have HIGH odds of success
they should have again a good guide that knows the land and how to hunt elk on it
things like packing game out, handling game , also should be included and done by an experienced person
if its a horse pack trip,
Horses should be included and they should be GOOD horses at that too! used to inexperienced riders and able to handle the terrain!
next
Lodging should be include as with all meals!, be it a good camp tend set up, or a lodge /cabin set up!
and all transportation each day from lodging to hunting lands should also be included!
as at 5 grand for a 5 day hunt that is a grand a day, and a GOOD outfit should be able to do a LOT with a grand a day on income! and provide a hunter willing to pay the 5 k a good honest legal hunt !

NOW as for he above with what should the difference be when hunts start to cost more $$
one would be BOTH accommodations, meals catered to SPOIL a hunter when in camp/back at lodge!
NEXT, LANDS<
they should all be extremely well managed, limited to number of hunters per yr, size of game harvested and so on ALL private lands, , extremely well managed , so anyone paying larger amounts of $$ has a chance at a true trophy class bull! and not hunting lands that were over hunted, game over called or pressured, and must have healthy populations of elk at TIME of hunt!
they should be getting an extremely experienced guide that does about everything but pull the trigger, letting the client decide how much they wish to do on the hunt!
when your getting into high dollar hints, its not really about hunting, its about someone typically getting something they wanted, but never got in there life time and are now in a position to basically PAY for it to happen!
sorry if this offends anyone, but its about as honest as I can be about it!

there are again tons of FREE DIY type hunts a person can still do, if its NOT about getting a animal and enjoying a hunt and if you get an animal a bonus
this is what hunting is.
when your PAYING big money, its a business transaction more or less and the person paying is expecting odds tipped in there favor due to the paying part of the transaction, the higher the costs, the higher the success rates should be, and again the accommodations and quality of the land and people involved in the hunt!
to the really TRUE Trophy guys, with deep pockets and little desire to have a REAL hunt, , most of these types will pay big $$ and go to a high fence type set up, and PAY for "X" sized elk, and go shoot one!
places like this are all over any more, just like they are for whitetail deer, high fenced set ups, where success is almost a guarantee !
