Have you considered putting this in the [url=https://www.roleplayerguild.com/forums/6-arena-roleplay]Arena Roleplay Subforum?[/url] I realize not all the events are strictly combat-oriented, but they cater pretty specifically to your premise if nothing else and they have several roleplayers experienced with this sort of thing.

If you do not feel like having the whole thread moved, you might also consider just posting a connected interest check there.
