I'd suggest you to

A) Create a simpler game, (mainly because it seems like you're quite new and working on that game as a single person)
Simple doesn't mean bad or boring. If you're not the 3d-and-animation-guy, keep the graphics really simple and focus more on the gameplay.
Try something too big and you'll end up with nothing but an idea and a bad, unfinished game.

B) Team up with some other people who want to work on the same project. However, it seems like there are not a lot of people around who are experienced with animating...
