I have a small one-man business handing registrations for juryed art shows (think white pop-up tents in the park full of artists selling things) that's called The Online Jurying System at http://ojs.biz http://ojs.biz. I built it on CakePHP, PHP, MySQL and VestaCP hosted on a Digital Ocean droplet. It's currently using PayPal to handle the credit card payments but I'm in the process of adding an option to use Stripe. The accounting is pretty simple, I keep a portion of the artists registration fee and the art show gets the rest effectively making it 'free' to the art show itself.
