Hi @Padino
That sounds like a very interesting (!) project. 
May I as a moderator in this forum ask what you are suggesting/sharing by posting here to make sure you get the best support?
(1) Do you plan to share a CHALLENGE about writing your DIWO handbook. Framing it as a challenge could allow you to ask people for specific help for example with graphics or language.
or do you
(2) Want to write an ACTION on how to replicate your idea/solution everywhere in the world.
Maybe you want to do both?
In this case I think it would be good, if you set up an individual topic for both projects (or just start with one). And then post specific requests for example.
I am happy to help you framing both endeavours.
