Late to this thread, but we did a private, guided safari in Namibia, and it cost nowhere near $2000/day. My brother did a self-drive trip in Namibia, but did do some guided game drives. (Some places, such as Erindi, require that you go with their guides in their vehicles.)
Note that Etosha is HUGE, and there is much more to see than what one sees at the couple of waterhole lodges. That said, something that is different about safaris in Namibia, vs East Africa, is that the animals tend not to travel in large herds, and, during their winter (our summer), which is the dry season, animals do tend to congregate at waterholes. But we saw animals not at waterholes in Namibia, too, including zebras, giraffes, ostriches, oryx, springbok, kudu, wildebeast, desert-adapted elephants, a black rhino, and two white rhinos.
I was very glad to be with our guide on more than one occasion. For instance, when we got a flat tire (roads are better in Namibia than in many other African countries, but there are still places with sharp pieces of rock sticking out). We didn't have to worry about changing the tire ourselves. Also, when we saw the black rhino and the desert adapted elephants, our guide knew how avoid agitating the animals, how to read their body language, and what to do about it. In contrast, a self-driven vehicle with several tourists in it had been attacked and overturned by a black rhino a couple of days before. Also, we would never have spotted the black rhino without our guide's sharp eyes, and we would never have found the desert adapted elephants, which were in a dry riverbed that our guide drove into. He also knew how to drive in the dunes and not get stuck.

The cost was N$ 49 740.00 in 2017 (which was about $3750 US at the time) for 11 nights/12 days for the two of us (i.e. not each) (and, yes, it was 12 days. We were on safari practically from the moment we left the airport until we arrived back at the airport).
Included:
· Isuzu 4x4 Double Cab vehicle with full vehicle insurance (seats 3 passengers plus guide)
(We had the option of choosing a larger Ssafari vehicle with 7 seats and big windows and pop up roof for game viewing. This would have been more expensive and wasn't really necessary for 2 of us, since one of us could sit in front and the other, in back, could move to either side.)
· Fuel for tour
· Guide (24 hours there for you)
· All accommodation (Mid class lodges (which were very luxurious to us--we could have chosen different classes of accommodation for more or less $.))
· Most dinners and breakfasts (except not dinners in Swakopmund)
· All National Park Fees entrance
· Welcome package
· Fridge on Car
· A/C on Vehicle
· Bottle Water on vehicle for duration of tour
· Passenger liability insurance
Excluded:
· All flights
· Meals not stipulated like Lunch (average you can work on N$ 120 pp/d if need to) (Except our guide made us lunch one day--a delicious braai in the dry riverbed while we were searching for elephants. Oh, AND he brought us sandwiches on our arrival day.)
· Medical and travel insurance
· All activities except when stipulated.
· Any Drinks at lodges or on tour. Except water on Vehicle
