Hello, honestly I don't know Renpy... But I've learned a lot of different programs and I could most likely figure it out. I've done a bit of work with making visual novel type scenes for a tactical game I'm working on in Godot but it's not going to be as in depth as what you're most likely planning on.
I'd wait and see if anyone more proficient shows up with interest in the project but I'm open as a backup option. I would like pay of some sort but I'll most likely be one of the cheapest options around.
Here's a post I just made which is pretty much my portfolio. It's a bit long winded.
