Hi,
As your job post you need white board animation for courses, each chapter is 15 minutes Video with Audio. I have already worked on white board animation.
I have eight years of experience in graphic designing and already worked on: (Cartoon Characters, Illustrations, Kid Books, Artistic Designs, Caricatures, Logos, Flyers, Banners etc.).
You can review my designs in my portfolio:

Thank you for your consideration,
Shahrukh
