You should do a kick starter or something to help fund this.
As much as i love this idea, there can be a major downfall to it as well.
1) the overwhelming amount of people that would want these products would backlog him immensely.
2) what would a total dollar amount goal be?
3)he cant make every single one of them all by himself! That would take forever!
Yes it is possible with the right plan and thought but ultimately it will be up to him if he wants to pursue this long winded road.
