Why do you want to buy clients? Are you hoping that will help jumpstart your business? Sometimes, it is easy to buy clients / hosting companies at the end of summer when schools start up (teenagers start a company but then cannot maintain it while in school).
Getting your own customers is usually a better way - they are yours and they don't feel like that are forced on to you.
If you have enough money to buy clients - you might consider putting that money into advertising or other methods to let the customers come to you.
As far as your location, it might matter to some people. Some won't ever know and some won't care. A lot of people - where can they get the best deal. Focus on customer support and maybe reward your customers if they refer others.
Speaking from personal experience, do what you want in your own country. Don't go in the USA / Canadian market. It will piss off your members and will leave instantly. Looking at your grammar, and overall sense of professionalism, stay in india. (not a racist flame)
