Hi Gary,
Thanks so much for getting in touch! I’m really excited to hear you’re looking into our plugins for your organization and I hope they are a good fit for the site you’re building. 🙂
We do indeed have a nonprofit program and I would absolutely encourage you to apply. If accepted, we would be happy to grant you a free license for either Events Calendar PRO or Event Tickets Plus. Here is a link to more information about the program that includes a direct link to the application:

As far as a demo goes, we offer a full refund on all our products within 30 days of purchase. We do that to give everyone a good amount of time to download, install, and try the plugins with their own sites and return them if they wind up not fitting your needs for any reason at all.
Does this help answer your question? Please let me know. 🙂
Cheers!
Geoff
