I'm clearing a lot of trees. I have a logger taking a few of the larger trees, since he's insured and they're right next to the house. I'm cutting down the rest, and I really don't have any use for the wood. If you're willing to take the limbs and brush, you can also have the rest.
I may or may not be persuaded to cut up the trunks, depending upon what length you want them cut into.
I may also be persuaded to cut down some trees for you if you have some on your own property that aren't likely to hit something (I'm not going to risk crushing your house or somesuch - that's what folks with insurance are for), but maybe are bigger than you can handle with your saw (I got this beast so I can do things like cut steel or concrete - it's overkill for most trees).
