Simple Video Animation Needed

I have a small clamp which resembles one half of a set of handcuffs. It is used to secure the handle to the hitchpost of manufactured trailers, e.g. horse trailers and boat trailers. I would like a short animation that shows the clamp, then it opens, then it zooms onto a trailer hitch and handle, then closes, then a padlock comes in and locks the clamp securely. That's it. Nothing fancy at all. This can be written in Flash, as an animated .gif, whatever. You tell me. I just need for it to be very clear so that people fully understand how the product works and SEE IT. I want to put the video on a website so the video needs to be playable across the web. The video window should be *approx.* 350 width by 300 height (pixels) and approximately 6 - 8 seconds in length. I have attached a .zip file of images of my clamp and will gladly provide more, especially since it's hard to see the clamp on the boat trailer hitch in the pictures provided. I want to make sure you fully understand the project! It really is this simple. Please send any messages for clarification - I promise to answer quickly!
