Just to repeat something:
when I was in Namibia the most hiring of pilots was done between February and June. 2010 may be different though....
Also, in 2007-8 you could get a room at the backpackers for between US$10-15.
The 20 British pounds/night that someone mentioned above seems a bit steep to me! If you're really tight and think it might take you a couple of months to get a job sorted then buy a tent and pitch it on the backpackers' grounds for around US$7-8 /night... I lived in a tent for about 6 weeks - good character builiding!
Cheers!
