I've actually been to Namibia. I went a couple years ago with these fuckers
http://www.desertelephant.org/If you want to "test the waters" and figure out what the country is like, that's not a bad way to do it. You basically spend two weeks in the wilderness building shit and camping outside. It's pretty cheap, you're basically paying for your plane ticket down there, and the guys you stay with tend to know a LOT about the country.
A couple things I've learned that might be helpful:
1. Spiders the size of your hand & parabuthus scorpions. It's not as bad as Australia, but you're gonna need to learn to shake your boots out. Getting bitten/stung is going to be an eventuality so you fuckers should plan for that.
2. I'm pretty sure there are lions and shit as well, but you have talked about getting guns so that's not as much of a problem as 1.
3. I stayed in Swakopmund.
https://en.wikipedia.org/wiki/SwakopmundReading the wikipedia page, there are a couple things that might interest you.
a) Strong German/Dutch influence. If you're a pro-Aryan /pol/tard this should make your dick rock hard.
b) Large uranium deposits. Namibia, despite being sparsely populated, actually has a fair amount of minerals. When I was there, there were a couple of French investment companies looking to develop the area, so it's not "a worthless wasteland".
4. Briefly stayed in Windhoek

5. Goat herding is popular down there. Meat is a status symbol, vegetables are what you eat when you've run out of meat. You should really look into goats.
6. Elephants will destroy your water supply and dig up your pipes if you don't bury them deep enough and build walls. You don't need to build high walls, elephants are lazy and a shoulder-height structure will stop them, but you need to do it because water is precious.
That's it, I hope I've enlightened you, glhf I hope *this* project goes better than all the other "INNAWOODS INTERNET UTOPIAS" that are planned but never happen.
