Create 2d animation - Earth science for stage 1 kids

We are educational software company who uses animations to explain lessons to kids from stage 1 to 6. We would like skilled animations to create 2D animated lessons. We will supply all sounds such as soundtracks, and voice over. You are to complete the animation with your own dummy voice. We also have a Team of animators who will complete the animation with the final voice over and soundtracks. We will supply flash file of all views of our characters so that the characters you use will not be different from animations completed by our own animators. We need to produce a number of lessons each week. Our Team of animators cannot do all. So we are issuing some of the lessons here so other freelance animators can complete. The script for this lesson is attached. Thanks for bidding.
