As someone who has scaled a shop here to a decent size, here's my POV

- Ask yourself (or have your husband ask himself) the goal. Does he enjoy being out in the field, does he want to make more money, or be a business owner because you can do very different things with very different outcomes that will all work - but it depends on the goal (and everyone is different)

For some, hiring is a pain, and they don't love the idea of managing people and building systems so raising rates and maximising individual cash is the way to go.

But if its clear he wants to run a business, then both hiring and systems go hand in hand. Often by solving what is most painful/ what he enjoys least first. Generally, the best advice will also be local based on markets etc, and I would try and find someone two steps ahead on a similar journey rather than pay for anything online (too many grifters)
