You ask if it is worth getting a timber person? I more than paid for the original construction of my pond by having very selective timbering done on 20 acres surrounding the pond. Nothing under 20" diameter, 6 feet high was supposed to be cut, except in the pool area. (the guy did end up cutting several very nice White Oak at 14")
A timber cutter will normally come in, and follow your rules on how any skidding is done, and where roads/staging areas are built, but if it won't make the guy money, he won't do it! The person I hired went 60:40 in my favor because I was very lucky to have a rare, single, $20,000 walnut tree I had already cut, aged, and had graded (48"Diameter at the base, 39" small end and 38' to the first defect, very dense wood and straight as a pool cue).
Few cutters will touch tops and waste except to keep paths clear as that burns a lot of profit up fast!
