That surely should be up to the people involved to decide and there is no real pattern for a rate that I've seen or can imagine. Many factors such as quality of the hunt are impossible to place a value on. Guess a fair price is one agreed to by all parties involved! I might put more emphasis on quality and on liability to the landowner than anything else....others might have other things they would focus more on.
There is more involved than just price, IMO. Costs of raising the game can be at least roughly estimated, costs of landowners liability insurance, game enhancement costs, whether or not housing and meals are included, having guides who know the particular property and game patterns, time the hunter spends on the property scouting his hunt, criteria for good sportsmanship during the hunt, requirements/agreement on type, size or other criteria for game to be taken, amount of area available per hunter, liability questions, and whatever else the parties involved want discussed and agreed upon should determine the price of access and use of ones property. Maybe even the price the hunter has paid for his gear! And property taxes the landowner must pay may even be a factor. And why not? Those taxes have no basis on ability to pay and are a significant cost of doing any business requiring a land base.
Frankly, we have had some good and honorable self guided hunters......and we have had our land and our trust in hunters abused by some real slob hunters who chased deer unmercifully, who lied about access, and who claimed they were on someone elses land and wounded an animal which then entered our property......and more. All of which makes one more than a little disgusted and wary of so called 'sportsmen'.
