I don't really know what you mean by professional hunter? A guide? An outfitter? What exactly are you wanting to do with the property? Sell hunts? Lease the land? How big is the place?

Sorry to ask so many questions but your post was a little vague.

Maybe try putting up a flyer in a local feed store or outdoor store. Also might try placing an ad in a local paper for whatever it is you're looking for.
