Your trees where dropped the op's tree can not be dropped according to them there is no where to drop it. I know i have a huge maple in my back yard that is the same it will need taken down a piece at a time. and yes that is very dangerous and expensive. You say yours can only go one way the op says theirs cant go anyway that is the differenceI still think that price is insane. I went and dug a picture out from when I had trees dropped that I mentioned a few posts up. There were 3 more in front of the house that he took down as well. One of which was about 10 inches from a power line leaning right towards it.
All of these were leaning right over my house. That one huge branch completely shaded my deck.
