Inspiring idea, Kristina! Perhaps existing mobile services could also situate themselves at centralized pickup and drop-off sites--such services as mobile health and dental clinics, and even healthy food trucks like Mr. Okra or La Cocinita (the latter would likely require a subsidy). And I, too, love the photo!
Hey, Candy! Your idea sounds fantastic. It would also be cool if somehow you could collaborate with an existing non-profit like Operation HOPE, which holds great (and free) business development classes open to the community. If you haven't already, you should check them out.
