Tens of millions might be stretching reality a little bit.

I'd venture a guess that a significant chunk of currently registered small businesses are not succeeding, and again another chunk that is profitable but the owner/operator doesn't make a significant amount of money.

There are around 28,000,000 registered small businesses. Of those "10's of millions" are not absent owners.

Not saying he can't do it, but finding someone competent and trustworthy isn't an easy task.
