Hello MichaelD,
Gotcha covered on the multiple postings. 😉
Having customers pay to submit events has been mentioned a handful of times, but isn’t a highly-demanded feature and not our highest priority at the moment. I understand that it would be very useful to you though. But as Leah said in the other post, that would be custom work which is beyond our scope. I can give you a few leads on developers you could contact, if you’re interested. But I’m not aware of any services that do what you’re looking for, however that doesn’t mean they don’t exist.
Sorry I can’t be of more help.
