Can you build ticket site on magento?

Looking for someone who can develop an event ticketing system built on magento. I have someone who can handle all the skinning, but I need someone who can handle the entire backend. Basically I am launching a site that is geared towards small independent concert promoters. Im fairly familiar with Magento's capabilities and for the most part, it will work for us almost "Right out of the box" What we really need is someone to make it possible for our users (independent promoters, venues) to ad events to the store, and view sales reports for their events only.
