I enjoy the challenge too, I do hate cutting so many trees down.
One suggestion is to never agree to wait for insurace settlement, get a sig. with agrement of payment on completion. Escpcialy if working for the insurace agent many will try to dicker the price down. Their job is to reduce liability to their underwriters.
If the job is big, have the homeowner check th policy on coveraing debrise cleanup, some have a $500 cap on the comprehensive.
If the insurance only covers removal of damage on the building, they may try to not pay for the chipping. Insist that it has to be cleared from the work area for safety reason.
Always take pictures, a poloroid is cheap cya. (for any removal, I've been tod to take a wrong tree down, and a local Country Club had a contractor remove a wrong tree "hey, that's the one you flagges!" it was a huge willow that was key to play.)
