Flash Animations For Science Revision Site

I need a flash animator to create 50 flash animations all of approximately 5 minutes in length. The animations are for GCSE science in the UK (that is age 16). All the animations have been thought out already and storyboards will be provided. For many of the animations you will be able to ruse sections or parts from previous animations. They range from very simple, such as the Heat Transfer ones which manly has particles moving about, to more complicated, such as Power stations. The animations need to be provided in a SWF format so that i can add narration over the top, if it is much easier i could possibly provide the audio clips already but this is not preferable. This is the first set of animations I need for my new website [login to view URL] which is in development. If i am happy with these animations there would then be future work to do about 40 more Physics animations and then 90 Biology and Chemistry animations as well. Although I have not posted a job before, this is a real and serious project. I currently run the website [login to view URL] providing revision DVD's for Maths but want to now expand to provide online animated revision for science. A breakdown of all the animations can be provided.
