2 minute Flash Demo

I am looking for a 2 minute flash 'Elevator Pitch' Demonstration.

My company is about to launch a new web based collaboration Portal, this demonstrator will be on a our website to help explain what we do.Collaboration is a powerful capability, that often cannot be explained well in 60 seconds by words alone.

I am looking for someone to help me build a flash based demonstration, that visually shows the capability/application and power of this solution.

ideally this demo will be between 90-120 seconds and with animation and voice (or clear smooth running text on the screen), to show what this system is, how it can be used and what the value is.

This project will take a very skilled Flash technican who will need a lot of flair and creative imagination.

Previous examples of similar work are essential.

Here is an unrelated example of what I am looking for -
