Animation for educating children in LNG

Hi
I need someone to create a simple children focussed animation. The animation will be to explain briefly how natural gas gets transferred in to a liquid form. Then it is shipped and transported around the world. Then how it is pumped via an offshore terminal to a Regassification plant and converted back to a gas. We will provide the technical details but we need the producer of the video to create a child friendly script and animation.
So in summary, please provide:
1) A simple child friendly script
2) A 2 minute animation showing how gas is converted to a liquid (not too much detail) and then why it is converted (can store 600 x the amount in liquid form). Then it being transported around the world on liquid natural gas carriers. Then arriving at a terminal (we will provide photo so you can replicate in cartoon form). Then the liquid going up the terminal and then it converting to a natural gas. Then being pumped sub sea to a receiving facility. We will provide the detail for the script.
We will then go on to explain some of the different roles we have here at the terminal. If we send some photos of people - can these individuals be 'cartoonised' and feature in the animation?
3) An English speaking voiceover with tones and style appropriate for children (mix between 5 years old to 12 years old).
4) Insert our logo for use with no other watermarks or logos on the video.
