Hi – great question!
It sounds like you need a solution that allows some users to submit events, but also to retail tickets to those same events. If that’s the case, a combination of our core, free plugin The Events Calendar – plus our awesome Community Events and WooCommerce Tickets addons – could form a solid platform for you to build on.
I suspect there would still be a few challenges to solve to fully meet your spec (disbursement of funds, for instance) but something like the above combination would likely get you 90% of the way to your goal and save you immeasurable development time.
As you mention Eventbrite, I also wanted to drop a note in that we have a plugin integrating with that very service (in case integration with Evenbrite is a possibility for you).
I hope that gives you a few ideas – but please don’t hesitate to let me know if I can offer any further guidance.
Thanks!
