I want to build a site that allows subscribe, then book time slots in a calendar. Booking a slot will cost an amount based on criteria the member selects in a form. I'm thinking the subscription part of the site will be built with Membrr, and the calendar will be Solspace Calendar.
The part I'm not sure about is how to charge users to book a slot (effectively charging to create an entry?).
Has anyone done something similar, or have ideas regarding how I might implement this?
Thanks in advance.
