I'm looking to do ticketing for Manifold's dating show. The show will place at theater in SF over the course of one evening. We'd ideally like to distribute ~300 tickets. I'd like to be able to sell some tickets in USD and some in mana. I'd also like to have early-bird tickets that sell at a discounted price and VIP tickets that cost much more than general admission. What software should I use to handle the issuing/sale of tickets as well as the check-in process for the event itself? I'll pay out some portion of the the bounty to any answers I find helpful.
