I definitely need to start using FancyHands (got the email from the guy who created it recently about how he was killing an old company and putting all effort into FancyHands). Unfortunately some of my current tasks require calling my lawyer and doing some other things that really only I can do.
I do need a dentist though, and a handful of other things. Time to delegate!
There would definitely have to be some great marketing for this to not seem shady.
A van wouldn't cut it - you would need a bus.
Can a hygienist practice independently?
I assume it shows up once or twice a month.
If you're just talking about, "we come to you", that doesn't seem like a real compelling service. Dentist visits are rare and important, so I'm willing to invest a little more, and it seems like dentistry in the back of a truck would be limited. Much of the equipment at a dentist's office can't exactly be thrown into a truck.
