for that kind of capacity i dont think you ought to be looking at any set up of your own
there are clear possibilities of doing this within other existing capacities.
If you are planning this as a business then may be you can look at ownership in part or full or some such structure
In your earlier posting you had indicated hyderabad as your proposed destination.
While i have nothing for or against hyderabad i would think you should consider a host of factors before you can finalise destination as also vendor you would use
While working with a third party vendor you would like to look at his strengths and weak points and butress some of them through special structures before you go ahead
