Hi Rob,
Thanks so much for your interest in Community Events! While Community Events does not currently include built-in support for paid event submissions, we do plan to incorporate this functionality into a future product update. We don’t have an exact timeline for when this feature might be available, but you can follow our UserVoice page for this feature to keep up with the latest updates on its progress:

If this feature is critical to your planned project, you might consider enlisting the services of a third-party developer to add this functionality for you. We do maintain a list of third-party developers who work with our products and who would be glad to discuss the details of your project in greater depth!
I hope that helps to get you started! Thanks again for reaching out, and let me know if you should have any other questions!
