@OP, IF you are concerned with getting a fair price, if you are concerned with how your property looks after the cut, if you are trying not to get screwed ... hire a professional consulting forester. MOST private property owners only do one or two timber sales in their life time. And there are 50 ways for an unscrupulous logger or timber buyer to skin a property owner. A professional forester may not be cheap. But, is money well spent.
