Sorry for the terrible subject line, I can't think of a better one!
I've been asked by someone who organises charity bag collections for some software to help them organise themselves. Ie they send people out to drop empty sacks (or leaflets) through people's doors, then go back to collect them, and they want a way to basically manage that process to make sure areas get covered properly but not more than once, to record how many bags they get back out of each 100 empty bags they send out, etc.
Any suggestions? I figure there are similar potential uses for such an application out there (eg Kleeneezeeee or whatever they're called), but half the problem is working out what to search for.
