I am helping a friend with their Wix Website. It is a services based business, where customers can book a 1-on-1 session in their home, and a nurse will come to them.
They would like to introduce “Group Appointments”, which means, 1 person can book an appointment for 3-6 participants (NOT a class), where the nurse will go to 1 address and service the 3-6 people at the same time.
Now… Wix has no solutions for this at this moment. There is no option to book several appointments at once and no option to add extra charges to a booking.
So I need a creative solution how to go about it 
I need to have dynamic pricing available. If a client books a Group Appointment for 3 people, they need to select 3 services they want to receive (this can be 3 different services with different prices, 3 of the same service or any other combo). E.g.: Service 1 - $225, Service 2 - $200, Service 3 - $250. The total price should be, of course, the sum of the 3 prices = $675. They MUST be able to pay online (no in person payments are accepted).
How would I go about this? It needs to take staff availability from the Bookings calendar into account, so choosing a “class” as service type is not an option.
HELP???
