I've been tasked to create an online event management system. Ket functionality is:
CMS to update content dynamically
Interactive floor map allowing third party companies to reserve and pay for floor space
Online payment gateway
Hotel and car park booking
My first thought was Umbraco or DotNetNuke but I can't seem to find any modules that will at least get me started. Most of the modules are just fancy calendar views. The key is the interactive floor booking plan (much like a recruitment show) and payment gateway.
Any help appreciated.
