Create 12 Simple Explainer Videos on Classical Music

I am looking for someone to produce 12 explainer videos, each from 2-4 minutes long, on a set of Classical pieces (Vivaldi's Four Seasons). Text will have to be timed with specific parts of the pieces (I will give you the exact timings). I produced one a while back that looks a bit amateurish, but will give you a rough idea of what I'm looking for: [login to view URL] Please provide examples of past explainer video work, thanks.
