Well I really hope its worth it. I really can’t see worrying much about the pinch weld. I would have hammered it back straight and painted it. On my old Riv, after some years, I went to jack it up and the jack went right through. I just carried a 2x4 after that for emergencies. Never seemed to affect anything.
As far as the yews go, get a price first. I had a big triple river birch that was close to the house and the neighbors house. The tree service took it down for $250 including grinding the stump. They were done in a couple hours and all I had to do was watch. No grubbing tool, no grunting, chopping, hauling away, just watched.
