If you are going to tackle a tree that size you need to know what you are doing. First of all if it is a hazard tree you will be well advised to hire the best arborist in the area, if it is standing out in a field and could not possibly hit any thing you would still want some one that knows what they are doing falling a tree that size. You could loose half of your board footage when it hits the ground the wrong way.
Ok, now that the tree is on the ground, can you get equipment to the tree to handle moving it around? If not you just upped the ante. If you can, renting a piece of equipment like a mid sized excavator would be a real time saver. Bring in a tree service with a chipper to take care of the clean up since you are not able to just run over after work and spend a few hours a day.
Now you have removed all but the usable wood and can work around the tree. If you can not get equipment to the tree you will spend days just getting it down to pieces that you can pack out. Time will not be on your side. If you can get equipment to the tree quarter the logs up, have a portable-sawmill, come in, slice it up for you, load it on your truck and trailer, and make the necessary trips to haul it home.
It is hard to tell how much board footage is in a tree with out seeing it. Nevertheless, as a rough estimate and a round number let use 1,000 bft, that may be high. Arborist fees could be $10,000 easy, $1,000 for equipment rental, $1,000 for sawmill, plus the time and cost of transporting it. Who is repairing and replanting the lawn and other shrubs that may be damaged? You?
The $200 for the tree is just a drop in the bucket.
A better way to handle this would be to have the homeowner, which wants the messy tree removed, to pay for removal and clean up. Then pay you the $200 to save them the cost of renting equipment to get the big hunk of wood that they have no use for nor a way of moving with out costing them another arm and leg, out of there yard.
You can bet that they have had an arborist give them an estimate on removing the tree and are looking for a way to save them selves some big money.
So what it all comes down to is how much time and money do you want to invest in this wood.
On the other hand, you could drive up here to Oregon and spent $200 for a couple of nice 8’-10’logs that I have decked up. I can mill them into the sizes that you like and you can drive home. You saved yourself a lot of work and head aches and have a relaxing drive with out all the worries and time restraints. If you want to slice them up your self at home I can load them up for you as well. The logs are marked with a price and have no hidden cost other then the possibility of metal.
