So I found this organization--Kiva--that channels donor funds to field organizations, who then distribute those funds as loans to local entrepreneurs. These micro-loans are repayable in 6-18 months and can then be either re-invested, donated to Kiva, or go back in your personal account. Repayment success to date is somewhere around 98%. You can give as little as $25 to help someone outfit their retail shop, purchase solar panels, a bicycle, agriculture supplies, whatever. You can select which entrepreneur or group of entrepreneurs will receive your contribution.
I found a few entrepreneurs listed in both Congo and Mozambique. The field partner in Congo is a sister organization to HOPE International Development Agency, based in Canada, Christian-founded. This is also the organization that was primarily responsible for the development of aquaculture in the northern region of DRC that I visited in 2008.
I think it sounds awesome. I'm going to check it out a bit further and likely make a small loan. Would be the icing on the cake if I could locate an entrepreneur in the list who is looking to establish a fish farm. Check it out: www.kiva.org.
