Setting up Mining rig in India

Hi there, I'm from India and would need your suggestions in setting up mining rig in India. What are all things I should be considering with the as specific as possible details? So far: Electricity I have access to solar plant for low cost electricity. For the heating issue, I'm planning to use some mechanism to transfer for cooking or other work. GPUs are somewhat costly. Also is it still profitable to min after this halving and considering future burdens.
