Like this list as it pretty much says what customers want but what specialists should be supplying.
The customer however is not expected to know these specialists, trusted tech advisers are.
I would much rather be focusing on high skill, higher profit work than messing with a laptop screen or a dirty old printer. Unless you have the parts and constant practice its unprofitable to work on these sort of jobs. If your organisation has cheap enough staff, enough cash to buy or keep up to date on supply of stock, enough skill training and most importantly enough customers to feed a specialisation, you can provide these kind of services. I've tried a few of these in the past and got burnt.
I know people who can provide all the services mentioned, I resell most of them, those that don't have cash value immediately, get me work/reputation/contacts with the people we give the work too. Effectively I work as a hub and make it easier for customers.
