What about starting a mini car wash business - more to help out than make cash?
what you need:
Couple of buckets, sunlight liquid, a few cloths and water.
Find a reasonably busy road, and two unemployed guys that work quickly.
A sign that say "hand car wash - 10 minutes - R20"
Maybe a couple of directors chairs, newspaper and some shade.
R7.50 per worker per car and R5 to you.
Not trying to compete with the full service valet, just a quick wash for cheapskates like me. I am sure 20 - 30 cars a day would not be crazy but even 10 will give the guys some cash with very little outlay on your part.
Just an idea - but could potentially employ quite a few part-timers across the country
