I do not see any LM openings immediately due to the economy.
However, I would send a C.V. every 2 or 3 months to -
MK Airlines (particularly as you are from Johannesburg)
Cargolux, maybe even Air Atlanta Iceland
Atlas and Polar in the USA, as well as Kalitta and Evergreen
All above cargo airlines often operate with ride-along L/M.

Good luck.
