moving to Botswana

I am a 27 year old female journalist who has been working in the UK for two years doing voluntary work. I am writing a novel based in africa. And would liketo spend sometime in Botswana because part of the novel is based in Botswana.I would like a place to stay and information on how i can get a visa to Botswana and who would like to help.
i am originally from Uganda and love to travel. I would like to meet a group of young people who are honest and would like a friend as well. I am a christian as well. Please help!
