A friend of mine had some MASSIVE old oaks dropped on his land a few years ago. Even though he had them not brush/chip/haul the wood, it still cost him well over $1000/tree, then he and a bunch of friends took 4 full days to finish clearing up the area and hauling the firewood to his dad's place for his woodstove.

SHit is crazy expensive and 100% labor intensive. A good workout if you like doing that kind of stuff, though.
