Using JEvents as an Appointment Booking Extension

Has anyone successfully used Jevents as a Booking/Management tool. I'm in need of an extension that would allow a customer to book an appointment for a SPA. The customer would be presented with a calendar and could select an open date/time slot based on current availability. The back end would control availability and allow the business owner to accept or reject appointment requests.

1. Generate Booking Request Email to Calendar Owner
2. Calendar owner can approve or deny the request.
3. The customer would receive a booking confirmation email if the time slot was approved.
4. The calendar would show the approved time slot as unavailable on the front end or just show the time slots that ARE available.
5. Back end should allow configuration for business hours, holidays, black out dates, customer confirmation/rejection email communications.
6. If you have multiple employees, there should be a company calendar with individual calendars for each employee

If something like this is not available using a combination of the available plugins, it would be a great addition to the Jevents Offering and certainly worth paying for. You may also want to consider working with one of the companies that have an established Booking Component already done and see if they are willing to adapt their component to use the Jevents Tables as an option. Just an idea to make the best calendar option for Joomla even better!

Thanks for allowing me to publicly think through all of us and for any help or guidance you may have.

Thanks
