I didn't, but then he made some $$$ on me when I bought one of his old airplanes. Actually, he didn't MAKE any money on it. He sold it to me (with extra parts) for what he paid for it. AND, he's the guy who buys fuel at our field in bulk so that we all get the best deal possible. Hmmm. Pretty good guy I'd say. i guess that's why they do it. Because they want to. Not for the pay although, I do know of some guys who do charge for their services. To each their own.
