search job or home in south africa

I'm 20 years old, and I study in a french ingeneering school (ICAM).
From April to August 2007, I'll be in South Africa, and I would like to live in a south african family near the ocean because I do surfing.
I could give lesson of french, mathematics or physics for example.
Otherwise, I could help in the house or in a hotel/restaurant.
The job doesn't have to be for four months.
Thanks a lot for your reading.
Léonard.
