I have worked in Flash for nearly 7 years. I have seen other ads doing the same thing that you are suggesting. Also "Transformers" rings a bell :)
I would need about 40 hours (10 days x 4 hours) to complete this project. That would make it only 6$ per hour, which i think is very less, but i want to get started on this great site, so i'd like the opportunity to design for you.
