Animation Video

I need a 6-8 minute video. This is an informational advertisement. I'm creating a script right now. It'll be about 8 minutes long I think and it'll include various kinds of information about multiple products and multiple concepts. It's to be put in a lead capture website I am creating right now. So the video ought to be artistic to keep people's attention and not annoy them. I've seen a lot of animated videos on youtube that have styles similar to what I'm looking for: Flash animation type: (channels) LearnLiberty CrashCourse Black and white animation: MinutePhysics understanding the 10th dimension evmoneytv Other: CGPgray Vihart - photographed animation If you create animation similar to any of these styles, or just as good in your estimation to these I'd love to see what you are capable of! Other notes: If you have experience in writing scripts for this kind of stuff that would definitely be a plus because your input would be valuable! I might be able to record the voice over myself, but if you have a voice actor that would be great!
