Animations needed for GCSE Phyics Online Website

I need an animator to create 40 animations for GCSE Physics in the UK (that is up to age 16). All the animations have been thought out already and storyboards will be provided as well as audio files and any extra information to help. For many of the animations you will be able to reuse sections or parts from previous animations. They range from very simple, to more complicated but each animation is no longer than 5 or 6 minutes in length. The animations are for the website [login to view URL] which is in development. I have already had 10 animations completed but unfortunately the animator could not complete the final 40. The first 10 are in flash, but if you are capable of animating in HTML5 then this may be preferable, although I am more than happy with flash. 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 90 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. I would obviously need to see a sample of work before accepting a bid. I have added a breakdown of what all the animations need to contain and have also attached a couple of the animations that have already been completed. Hope that helps clarify more what i am after.
