Calendar-Based Booking System (in a website)

I need someone who can implement a graphical user interface for an online booking system. The user should be able to see a nice calendar view on which he can select a day and see which hours are available. The main application is already done, so your job is to: - understand my description of the system such as the specifications for the interface (you are fluent in German or English) - create a graphical interface that makes it easy for users to book in their preferred hour - implement a connection between your graphical UI and my system (based on MySQL and PHP) - implement an admin function in which I can manage the bookings You will get more information and the exact description of how your graphical part should interact with my system. You should be experienced in Javascript and Website Design, and you should also know how Javascript interacts with PHP, as your work will operate within my PHP system. It would be a plus if you were a native German speaker, but English is also fine.
