I need a very simple scaled down version of eventbrite.com. It doesn't have to be complex at all. It just need it to look professional and offer a few features to start.
I want users to be able to create accounts where they can list their events along with the number of seats available and manage the process. Posting events will always be free. Users should be able to offer free events as well as paid events. They will list/offer "seats rather than tickets. Again, they can sell seats to their events or offer them for free. If the users charges a fee for the seats, I would like to collect a % of the fee collected. Users should have the ability to print a seat voucher for the event as well.
Not looking for fancy graphics or flash, just simple script or code. Please install as webpage to a server so I can see how it functions.
