Where I live I can clean my car for $ 8 if I drive to a place and do it all by myself. It will take me an hour to drive there, clean it and get back.

I can get it cleaned at the carwash for around $ 21, that will take me 40 minutes.

Or I can make an appointment and give my car to a guy who cleans it for me, the cost is $ 35 and it takes me 10 minutes.

They all make good money. Even the guy who charges $ 35. But none of it is 'premium'. There's a guy in Derbyshire, England. He charges £ 7200. Now that's premium. But the market's too small for premium. At least where I live.
