Just so you know, 20 minutes is a TON of work for just one or two animators, especially if the goal is Disney-level quality. As a rough estimate, I usually tell prospective clients that it takes one animator about a month to complete one minute of footage. So if you'll only have two people working on this, it will likely take 10 months *minimum*. If you're okay with that, great, but it helps to understand what you're getting into.
I sent you a note to continue the conversation.
Not that I'm personally aware of. Seems like the vast majority of animators here are working alone, but that doesn't mean they can't come together for an awesome collaboration!
