I hunted with Ivory Tip Outfitters in NW Colorado near Craig for a couple years. Got elk both trips. He had really good lodging, food and guides but the price was 6k or 6,500 depending on which ranch you hunted. I was looking for a hunt for my son and I and called him this spring but he was booked up for this year. I did a lot of research on other Ranching for Wildlife outfits in Colorado and some private ranches in N Mexico. We could've hunted N Mexico this fall for about 9k each. And I spoke to a few outfitters that had openings and that was about the going rate for a bull hunt.
I ended up booking a hunt for us with an outfit NW of Steamboat Springs for next season. They are a little more than 7k for a bull hunt. I doubt you'll find anything good with lodging for much less than that.
I would give Tony at Ivory Tip a call and see what he can offer. I had two great hunts with him and would've gone back if he had the dates available for next year that I wanted.
