Booking Module for

Hi Guys,
I know a plugin so for my car grooming shop,whereby people can prepay and reserve a date and time.
Anyone knows of a plugin whereby it can:

1. Display a calendar and lets the user know which timings are available and how many slots are left (in 1 hour slots)
2. I saw a plugin but its not for opencart (http://codecanyon.net/item/booking-syst ... view/87919)
3. able to link with the standard opencart capabilities such as "coupon codes", "different price for users"

Many Thanks appreciated!

Hello Give a look at this plugin
