http://coinworker.com/ This site pays you bitcoins for doing small works like surveys, search items and submitting reports, etc. You make points from doing work and once you’ve reached 200 points, your points get converted to bitcoins and are paid to your bitcoin address. If you ask me, I won’t recommend this site as it will take a lot of time and effort in earning 200 points.

Cash management program,
http://developer.android.com/guide/topics/sensors/sensors_overview.htmland this is the basis for my idea, the current sensors in the Android phones, allow for distributed weather monitoring, and also quite incredibly Gravitational measurements for Mineral exploration, or measurements of the Earths Geoid(Gravity Map), as well as magnetosphere.
Other things that can be done, your friend can be a mobile store for locals, they roam around the communities, ordering up supplies in bitcoin and delivering them, give the locals that deliver the products the option to get paid in bitcoins or cash(zimbabwe dollars), using ripple they could even start a viable business model.
track down world wide and local merchants willing to accept bitcoins for payment to further strengthen the Bitcoin Community, specially the ones that are willing to ship to Zimbabwe.
maybe even a mobile university, where locals offer classes in exchange for bitcoins, how about this: Community member wants to be trained in something they offer cash or bitcoins, for someone who is an expert to be brought in who is qualified to teach, when the right amount of people or right amount of bitcoins is reached the expert sets a time convenient for everyone and begins training them all, with performance statistics and feed back from the community education can take a great leap forward in Zimbabwe. Distributed education system that is based on an on-demand model.
Distributed rental system, where a local community member can rent out their idle and unused equipment for bitcoins or cash, for a small fee a local can go and pick up the equipment and deliver it to the person who needs it and come back when their rental is up... risky but if everyone knows everyone else and it is all in writing, the system becomes legally binding, since both parties know each other and the intermediary has setup the proper legal documentation with records of both parties agreement to the contract.
The whole point is taking what is scarce and difficult to come by and distributing it to the masses for a fee that will make the Expert in a subject, the owner of rare expensive equipment, or the community members with construction/plumbing/surveying skills be rewarded according to their worth.
by worth I mean that for example: lets say I explain further about the distributed construction system: A skilled labourer helps at a site, if the site is inspected by a Verified Expert Engineer and the house owner approves of the work, the skilled labourer gets points for being on a good construction site that delivered what was promised... if not they receive a bad report. the higher ranking a person becomes the more they can set the price for their work since it is known that they are a good worker who delivers.
this can be implemented in a distributed manner by a supply and demand marketplace. Owner wants house repaired/built pulls out their Android phone goes to the Construction app, marks down their construction needs puts down what they can afford, If they are cheap the High ranking Engineer doing the dispatch will send qualified but unproven workers to do the job, they inspect the work afterwards if they approve the labourers get a recommendation to a higher rank of pay, same can be done for the engineers and foremen, even other professions scientists, accountants, economists, civil engineers, etc. can be made available on demand to the community for a fee worthy to attract their attention and high ranking merit based experts to inspect their work.
My models are based on my belief that the people should decide what they need, I cannot choose for them, I am not a mind reader, they have to choose what they want and someone out there will have it, but of course they have to live as well so they must be compensated for their efforts.
