Friend of mine makes hourly what many people earn in a week ($1k hourly billable), so while they lived in LA it made sense to have someone drive them from the airport back home because what should take ~20 minutes at most usually took 2 hours.
During those two hours they could work, and thus make money, it didn't make sense to drive themselves.
Their company hired a particular car hire service and the drivers would get rotated through a schedule, but they ended up having a particularly good relationship with a particular driver.
So they dropped the contract with the company, and basically just paid the one driver himself, basically a personal chauffeur, but with a schedule that is known two weeks ahead of time, with some emergencies, but not 24/7.
Eventually this allowed said driver to buy a couple of cars, and start a company himself, while always making sure to take care of my family member first and foremost himself.
They trusted the driver with their children, and for certain purchases the driver would either go pick up items (such as jewelry/high end clothes) or their driver would drive a consultant (personal shopper) to go do the shopping/pickups.
My friend moved away from the LA area, but used the same driver for ~6 years or so, the driver now runs a high-end private car hire service that offers services to cater specifically to people that need services like that. No advertising, word of mouth only, and everyone involved is highly vetted and trusted.
It's pretty amazing how much time you get back when you can pay someone else to do the things that take time but don't really provide happiness in life. Such as cleaning/driving/cooking/household chores that the rest of us have to do ourselves, and thus is all billable time.
