Hi,
it's hard to to tell you how long and how much this project will cost you without any references or script. If you are asking for just animation and have a character and a rig already done, I am the best freelancer you can find:
I got out of university as the best animator in Montreal. I got in UBisoft, the largest game studio in the world and went up the ranks faster than anybody else, left and went to work at MPC, the largest VFX studio in the world as an animator.
If you are in need of a scene, model, rig, texture, lighting, animation and rendering. I am still the best bet that you have, because I work with a team of expert 3D freelancers that are ready to start on this anytime to make it the best project it can be.
Contact me anytime if you have any questions or to send me infos of your projects.
Thanks,
Raph D.
