Apologies if I should post this here. I work for Scottish Water and I am part of a team taking part in a global challenge to design and build a fully functioning app for hygiene promoters working in Nicaragua in places such as Bilwi. As part of the legacy for our app we wanted to build in an advert for advertising. We potentially have a sponsor from Scotland who will do so for the first year. However, the reality is their advertising will be of no use for the people using it. We wondered whether advertising for a company that does for example wind up torches might be a suitable sort of thing to do and what thoughts are on the possibilities are of getting a business local to Nicaragua on board? No problems if this isn't appropriate and has to be deleted :)
