Hey i want my home paid with btc 2, you are welcome to Nigeria, this your name attracted me to the thread. Without wasting my time let me go straight to your questions. If you want to establish Mining Farm in Nigeria, it is a developed idea but the country can offer you large place of land if you need it. But electricity is zero that you have to buy your electric power generator. And also you will pay tax to the government. Then before you come you have to have a friend friend Nigeria who will direct you where and what to do.  So that if you want to do in the room he will provide for you or in the public place. The cost of electricity is very low but undependable.
