The term KPO: Knowledge process outsourcing was coined around decade and half back in United States and at present India is a global KPO hub for rich talent pool and cheaper charge rates.
Recently a new trend is been followed, i.e. of weekend analyst, wherein people with 2-9 years of experience in any stream of science working in business, finance, intellectual property and market research work as freelance analyst in weekend and the price charges ranges from 30 to 80 dollars per hour.
At present there are more than 80 or so small and big KPO's in India but I hope by the end of this year the number's will cross more than 300 :)
