I have a friend who is urgently trying to build a booking system.
In short:
The goal for the website is to offer a robust and easy to use web-based booking system for dance studio owners and their clients, the dancers. Both groups should be able to log-in, and for the studio owners this will offer them the ability to adjust their profile, and manage and check their agenda. For the dancers it will offer them the ability to search for and look through the profiles of different studios, check the corresponding agendas, book and (in most cases) pay.
If anyone is interested or knows of someone who may be, please let me know!
Have you considered a template solution like:

PM me MRGreen, we've done a few booking systems for high-volume mountain resorts in Canada, we surely can help you with that!
