In order to be 'safe' then the minimum is two landrovers (ideally 2 max 3 per machine).
Route - will start from J'burg into Botswana then probably trans Kalahari to the Okovango Delta, Chobe then back through Makadakgadi (Top Gear challenge Salt Pans) south to Johannsburg. (Alternative would be west into Namibia)
Living conditions- tents on the roof of the Landy's, cooking over the fire - rough!
The trip will be pretty isolated, camps are likely to be sparse with a long drop toilet at best. Scenery and animals are likely to be the main attractions for going.
Times, two weeks next easter, would like to try and schedule so the mid or last weekend is the Easter weekend (April 3rd/4th).
Cost - Flight £600 at the moment 1/2 Landrover £750 then fuel and food (Cheap) I'd guess about £1800 would be a good total budget figure.
If you are genuinely interested, please drop me a PM (general questions, just respond to this topic).
Some points to consider - you will be living in close quarters with others for 2 weeks, animals are easier to see close up at the Zoo, I will need commitment very quickly in order to secure the land rovers and flights at a good price, mobile phone signals are a bit patchy at best

I have two already (1 Land Rover) and would ideally need 2 more people minimum and would not like to go past 4 machines (8 people)
