TL;DR: I'd like to help you developing this project. I have UE4 experience.
Loved your video on it and could relate so much to it. I teached my father how to play BF4 on PS4 and it took a few days until he could walk and move the camera at the same time. If you want, I'd love to help with this project of yours. I've worked (not professionally) with UE4 before for more than a year and am pretty familiar with it (I'm a programmer btw).
