My input may not be INCREDIBLY helpful, but regarding Cowboy Bebop figures, I'd suggest making at least one of Jet, and maybe 3 of Ed, though 2 is probably enough. It's not one of the fandoms I'm very into, so I can't necessarily speak for the fandom as a whole... A good percentage of people I've met have said Ed is one of their favorite characters, so it might sell reasonably well. And I'd suggest having at least one of Jet, just in case somebody wanted to buy a set or something. Though as you're the ones selling them, then maybe you know if that's unlikely.
