NDA is ok. However, provide some details (you've mentioned Sample Movies) for the expected animation flow, maybe even one PSD/or/FLA so we can check the work and give correct proposal.
The technical part of the work is not a problem at all, but the animation capabilities are quite important here, aren't they? Simply, I can help you is many cases, but I may not accept the job if you need a dancing bear or something like that.
Waiting on your replay with more details.
