If it were my tree, I'd leave it as-is. I think it's pretty cool. One thing the guy said, was the branches are lowering on it. He used to be able to walk under it, and now it hits his head(Maybe after the storm?). That got my attention. I looked on the back side, and I didn't notice the root plate pulling up, but it isn't my tree. I don't really see anywhere to cut that won't uglify it. His concern is parts falling on his dogs/kids, and I think it'll happen eventually with that section leaning out. Not really fall on anyone, but fall.
edit:
Regarding price... This is all fun stuff for me, so charge a nominal fee to cover wear/tear on gear, right? The problem with that, is twofold. For one, it cheapens the industry, and devalues the work as a whole. Not that I'm doing enough to affect local standards, but it's the point that matters. Secondly, I don't want to get a reputation as a guy that works for nothing. If I end up doing more with this stuff, that puts me in a bad spot, and it can be hard to get out of it. It also may become less fun working more and getting less.
The price I had in my head was around $500. Not sure how that compared to standards, hence the question. My goal is to hit about half what a company would charge.
