Box office software for a small high school performing arts center

I would like someone to create a ticketing "website" for our small (300 seat) performing arts center. I would like something similar to: <[login to view URL]> <[login to view URL]> I can't use these sites because for many high school events patrons aren't charged for tickets. I need a system that can manage the seating but with the possibility of having free tickets. This will probably just be hosted by the school internally and operated by myself or students trained to run the box office. It would be nice to have the possibilty to sell tickets on our external website as well (possibly using paypal as a payment method). ## Deliverables This is for a school Performing Arts Center with no budget allowance. This is why the maximum bid is so low.
