I already have the After Effects Project Files for the explainer video that I want.
However, these files are general files including lots of animated characters and other elements.
I want someone who can create a small story for the explainer video about our startup, and then use the needed elements from the files that I have.
I have bought these files from: http://videohive.net/item/casebook-marketing-explainer/7365728
So, if you're interested you need to have:
 Awesome After Effect experience and skills
 Good designing skills with photoshop
 Have created awesom explainer videos in the past
