Banglore is expensive because of the sheer number of IT companies there.
Come to chennai:
I can get you:
a posh OFFICE SPACE (Not a fucking apartment) for $60 in a posh area.
a sole proprietorship for less than $100
a decent grad for $200 - but not from the top Universities, though. Why? Because it's a cliched mindset that the best people come from the best universities. Have you watched Ratatouille?
"Not anyone can become a great artist, but a great artist can come from anywhere."
Please, I urge you to refresh this kind of attitude (Heavier pay = better quality employee, Better University = better grad)
