I'm sure it's a lot of work for him, mostly maintenance and cleaning. Also it sounds like the remote operation hardware and software are provided by him-- that can't be trivial and probably means he doesn't break even on a given telescope for a few months at least. Plus whatever it costs him to recruit new customers.
I bet he makes a good living on his labor and whatever capital he has tied up in the land, but it doesn't sound like an easy business.
