What to have ready before you automate
The build takes two weeks. How much of that is yours depends almost entirely on how settled the answers below already are.
Start with the list of what you actually sell, in the words your customers use for it rather than the words on your invoice. If a customer rings and asks for something by a name that is not on your list, that is the name to write down.
Then the prices, and this is where most of the delay happens. Not a range you are willing to discuss, but what a customer is told on the phone: the fixed ones, the ones that depend on something, and what that something is. A system that has not been given a real answer cannot invent one, and should not.
Then hours and availability. Real opening hours including the days you are closed, how long each service takes, how much gap you need between appointments, and who does what if more than one of you works there. That last part is what turns a booking into a slot in a specific diary rather than a note.
Last, the questions you already answer over and over: parking, whether children are welcome, what to bring, how long it takes, whether you come out to them. You know these by heart, which is exactly why they are easy to forget to write down. Bring them to the meeting and most of the build is already done.
