Well, you don't mention what the cost of electricity is there. That makes all the difference in the world.
If it is well below average (e..g, $0.10 per kWh or lower) then you would probably be able to mine at a profit using GPUs. There are many GPUs and completed, well-used rigs for sale so you could be up and running in a week or less if you really wanted.
Otherwise, there is a pretty long wait list for most anything else.
Mining isn't plug and play though. A "server farm" for mining is more like a career change than an easier way to get beer money.
