I do not think you are off-base in your research and consideration of the Peace River region. Some fine bucks come out of that area each year, and it should be within your stated budget. I hunted the Peace River on an archery hunt, and let an arrow fly the first evening of the hunt on a 189 typical.
Having said that, I prefer DIY hunts, and as others have mentioned, would look into a killer area and landowner voucher if it were me. Colorado would be a good place for that. Good luck in your search and hope you end up happy come this fall.
