calculation of  projects cost 
I suggest start  mining from 4 miner`s 
1 miner is 4.5th/s  (1 TH/s = 1,000 GH/s = 1,000,000 MH/s = 1,000,000,000 kH/ )
Miner cost in India with china transport 
1 * 1,20000 = 1,20000/-  INR 
4 * 1,20000  = 4,80000/- INR 
Power supply  ( there are many company`s  available in India all costing have difference ) 

1 * 15,000  = 15000 /- INR  
4*  15000   = 60000 /- INR 
( Power Supply costing is approximate it`s can reduce or increases also )
1 MBPS internet connection 
1* 3000 = 3000/-
