For $500, you won't get decent enough developers.
>> you can hire rockstart developers for $1000 to $1500.
Most of the 'rockstar' developers wouldn't want to risk it in a startup (which could fold out anyday) when they already are making > $1500 a month in that BigCo Inc. Unless equity is put on table for grabs, it's a pretty sad deal actually.
>> India does not lacks investors, it lacks an ecosystem.
Well, aren't investors a major part of the ecosystem? This would be more like the classic railroad paradox. IMHO, only after India sees good number of credible startups with popular products will VCs ever bother to look at India.
