If in some stage you'll want to create some kind of PoC, consider making a radio-play and some visual story boards, they relatively low in production costs, but can deliver a feeling that one will have experiencing end product, or can be a good medium in itself. Good luck with your endeavour.

Interesting – I was thinking about the storyboard myself. Since I'm no visual artist at all, maybe I could find such a person, who can help me visualize this story. Thanks for your answer.
