Create a video mock-up for artificial intelligence startup

Dear all, I would need to create a mock up video lasting no more than one minute. The video should be about artificial intelligence slide creation tool (powerpoint like). I would provide the slides and examples, but some-one would need to create video out of it. The focus of the video should be very similar to concept of [login to view URL] ([login to view URL]). Youtube: [login to view URL] There are couple of sketches that should be in the video: - person writing with pen on tablet/computer - person working with computer - self-appearing slides (as in autodraw) - playing with the same slides in powerpoint Since I am not an expert in video creation, please let me know how we can best create the content I need and what would be my tasks (write a storyline or sth...). It is mandatory that freelancer have portfolio of videos I can browse through. Please feel free to post your offers/clarifications here *Removed by Admin* Best, Matko
