Hi There,
Well i am a Malawian and I read your article on the net, I reckon there will be no problem as the country mainly depend on tourism and agriculture, the Malawian Goverment will recieve you with open arms. The people are very freindly and you will be able to establish your own place or by one. the best place to do this is along the lake shore. On immigration Issues, most of the countries in Europe including UK do not require visas to visit Malawi, I recommend that you go there first see what is like and then discuss your plans with appropriate authority. However, if your from UK you can contact the Malawi Embassy on 02074914172.
Wishiong you goodluck
Alex
