My dad is an elevator mechanic, and you'd be pretty surprised at what the job actually entails. He has to maintain legacy elevators with logic implemented by relay (1), up to brand new computer controlled systems. Over the course of his caree he has taught himself what would have been called an electrical engineering education 20 years ago. He had to become proficient in the basics of mechanical engineering, in order to run retrofits in older buildings. He had to become proficient in CAD, because half the work to fit new elevators in old buildings is custom fitment. On top of this, he has to be a project manager.

Now, add in liability insurance and other normal business overhead, custom tools, and niche market effects, and $500 an hour isn't out of the question.
