Have you figured out an authentication/billing solution?

There are lots of references to nocatauth - free, runs on linux. There are also lots of 3rd party RADIUS servers, very few of which seem to be at your price point (free).

Key to commercial service is captive portal which enables credit card registration/subscription. Seems like Wayport, Mobilestar, Boingo have gone to some trouble in developing proprietary solutions.

Have you priced the Aptilo solution? There would have to be a large market for a reasonably priced (not necessarily free) access/billing server.
