You should look upusername Huntquest on this site. His name is Kevin. I can give you his cell phone # if you send me an email. He has a very reasonably priced elk hunt in Colorado. I have been in contact with him and plan to do a deer/elk combo hunt with him next year. You could easily stay under $5k and get both a deer and an elk while you were out.
Here is his website. Check him out. He'll take care of you.
