Animation needed

I need a logo that shows a shark biting an object turned into an animation. The end of the animation will be the final logo. The steps of the animation: 1. Show a shark smiwwing into the logo from left to right. 2. Shark hits center of screen and turns towars screen 3. Shark shows animation swimming the whole time 4. As shark comes closer, the shark increases in size 5. As shark gets near, it jumps out of screen, its head snaps to the right and grabs the object and then comes back into slightly (like a shark normally does when it grabs its prey). The final pose is the logo. 6. During the movement you hear sound of swimming then sound of the snap to bite the object. Deliverable needs to be a video or flash object. Please post example work and quote. I will then show you basic illustration/logo.
