I'm currently getting stuff I can't do- art and music, specifically- through commissions, and I'd love to talk with you about paying you for some art! At the moment I'm desperately in need of environment/level art (as you'll be able to see with the ugly placeholder stuff I'm using for the levels right now, hehe).
I'm also looking into improving the character sprites, so if you're more interested in doing that kinda thing, we can talk about that too!
It's not a super small project, but there's also absolutely no rush involved, since I'm making this in my spare time and not planning on making money off of it.
I could contact you on your twitter if you're interested? It's cool if this isn't what you're looking for, though!
