OP - Are you crazy you want to setup mining in one of the costliest electricity rates available in India. It will not at all be feasible for you to get the profits if you start mining in India. Instead of that rent out that space and you will earn from day 1.
Office space is not suitable to mining but you can mine @ some idle space at home. As said feasible of mining is India is not profitable is a wrong statement... The electricity cost is approx 0.08 cent in India which is feasible to make profits by choosing a right coin for mining. If your interested PM me.
