hello. I know it's not one of the things you've mentioned in your list, but I am a beginner narrative designer/writer. I've been in a game jam before as just that, and I also took on a big portion of game design work aswell due to an unexpected shortage during it. I'm a big horror/psychological horror fan, and I recently decided I wanted to take a step into the game storytelling scene out of pure passion. I'd love to contribute as either an extra narrative designer/writer or even just someone to bounce ideas off of.
also, I've actually used Ren'Py before, though I never went anywhere with it, purely because I'm terrible and have no experience at making scenes and sprites...
if you'd like to have me on your team, you can contact me through here. I also have a discord.
