Hi, I can create the animations explaining diabetes millitus, anatomy, and whatever else you would require. I would create the animations in flash [unless you specifically require them to be 3d]. I have a good knowledge of anatomy and biochemistry as I have completed a B.Sc. program in chemistry [with a focus on biochemistry] in Canada.
As a native English speaker with a solid science background I will make sure your animations are accurate, easy to understand, and attractive. I will work for 25 per hour and can put in up to 25 hours per week. It should take 5-6 hours or less to create each animation depending on how detailed it needs to be and whether or not you have source images already [I can create the images if you do not already have them].
Feel free to contact me to discuss the project, and your requirements in more detail.
