Almost there with this. Two more things:
1) Is it possible to skip the selecting a Service Provider step after "Selecting a Service"? There is only one practitioner per service in this case and it would be confusing for the clients.
Currently I have this, but don't need to show the "choose service provider popping up after hitting "show available times" from the "Select a Service" dropdown.
2) Is it possible to have the dropdown text in white instead of black?
