I see, I don't blame you.
If you want a wilderness type hunt that's not a bad one, pretty country and rugged. if you want a higher quality bull your chances will be much better on big blocks of private land, there are a few outfitters in the central-east central part of the state with good ranches tied up. it just depends on what you're looking for in a hunt, and how much you want to pay, the price for average private land hunts probably is about the same but it will be quite a bit more for the best ones.
The thing to remember in Oregon is 90% of it is over hunted, getting away from the roads can help but private land is the only real refuge for animals to get some age on a regular basis.
