Book With Me
This page would be dedicated to booking an appointment online. It would have a link to your online booking, a popup, or whatever function your online booking software provides for this.
Works with Jane, Schedulicity, Clinicsense, and pretty much any online booker you can name.
You can also use this page to talk about other things relating to your online booking: simple instructions, scheduled vacations, issues people may notice when trying to book online, etc.
