Cost of a single-color paint job?

Sadly many have the same story
Sad but true. I have a people that I want him to talk to that are local, wish I had known them back when I had mine done. I am a bit hesitant to give my doc there numbers for fear of him having more troubles with them. One of the folks I want him to talk to is a neighbor. He does really nice work, and to the best of my knowledge has not screwed anybody around.....yet.....
