Good ideas.
Still only in addition to the “hands on” part, that to me seems extremely important, as no explanation ever can replace this experience.
Maybe @lieka might as well consider referencing or spreading some information like this one:

or the (outdated) cost-breakdown, that still gives some idea of where the money goes:

@lieka
Maybe you can ask the Fairphoners in Munich for some stickers; to spread them? 
And I really would point out NagerIT as well:
You can find some Information on their homepage (links in the post above).
