The Jiffy Lube/Quick Lube business model relies on cheap and barely trained kids who know nothing about what they do other than remove this plug and drain the oil, stick the plug back in and crossthread it, unscrew the oil filter and remove it, install the new filter and tighten it just enough to not fall off immediately, then top off all the fluids from the various hoses hanging from the ceiling and hopefully put the right stuff in each hole. Most people I know wouldn't want such an operation anywhere near their bike. What a lot of them don't know is that many Harley dealerships aren't much better, having their untrained newbies perform the "services" while the techs handle mechanical repairs. Experienced motorcycle owners are much more likely to use the DIY model, not just to save money but to be confident that everything was done and done correctly.
If you were to do this as something to keep yourself occupied and provide a little extra income in retirement, it might be worthwhile. If you were thinking of starting a business using the Jiffy Lube business model and hiring from the same labor pool they do, I don't think most motorcycle owners would be interested. JMHO.
