Web Application with FullCalendar, Vue Laravel MySQL (existing project)

We want to create an appointment booking system for the services such that the customer can click on the service and they get the time slots on the FullCalendar timegrid layout or similar to that. After clicking the time slot they can have a form to fill there information or can login/signup and finally they get the payment option.

The dashboard has been created for both customer and for the admin which shows bookings, services etc.
