[Plugin: Booking System]

Hi guys, i need a booking system plugin can do something like this…

Possibility for user to choose between different hour intervals.

For example:
– Haircut 30min
– Haircut and wash 1 hour
– Haircut, wash and dye 2 hours

After selection the calendar will change hour intervals based on users choice. For example if user has selected “Haircut 30min” the hours will be:
9:00 – 9:30
9:30 – 10:30
10:30 – 11:00

If user choose “Haircut and wash 1 hour” the calendar will change the hours to:
9:00 – 10:00
10:00 – 11:00
11:00 – 12:00
