Hello! I have worked in video editing and Web design for a couple of years now, I have extensively used JSON (and JavaScript), but I have no experience with Sezion. I think it will take some time to learn how to use it, and than create the video, so I would say I can finish it in 3 days (but maybe more). The Sezion concept sounds really interesting, and if you think we can work together, I look forward to learning it. Thanks!
