Hey Maya,
Thanks for reaching out to us!
We unfortunately do not currently have any general payment setup prior to allowing someone to submit an event. However, you could put something together like this by utilizing a Membership type plugin in addition to the Community Events plugin.
Also, our plugin is fully translatable and we already have a lot of translations already available that will display automatically based on the language associated with your WordPress installation.
Let me know if this helps.
Thanks!
