I'm looking at a web-based calendar which accepts multiple reservation and payment via paypal IPN. Customers will be able to look at the calendar, choose an event (set by admin in the backend), reserve it and pay immediately to secure the space.
> Admin will be able to set the following when login to backend:-
1) Period of date which event will be held
2) Multiple events on a single day
3) Maximum number of booking per event
4) Price for event
5) Special Pricing for first x number of booking for that event
6) Special pricing for a duration of period for that event
