Would it be possible to create a MVP and show that to commissioners / researchers / etc in your country?
You might want to get good quality research to support your idea. Good quality in this context means a cochrane review, or information from NICE (the UK organisation) or something equally rigorous.
I would be keen to hear your idea. Please feel free to email me.
Have you seen the Australian website "Moodgym"? And there are similar other sites.
