I would probably say 9am or 10am, depending on how far I would be travelling. I have had people enquiring about morning bookings and been in communication with potential clients to arrange it, but haven't had any that have gone through as people have ended up not getting back to me when I have asked for address/contact details or for them to make a booking. The earliest booking I have had that has actually happened has been 12pm. I am still quite new and yet to become full time, so maybe that will change eventually but, like various others in this thread, I'm not really a morning person.

Just recently had a booking at 6am, originally said no but the client offered double so it was too good to turn down. I’d always charge more for anything outside my working hours.
