Mr.Singh,
I understand that you are in a state of CONFUSIOn, about your requirement & need, as you have too much information to select from & have no knowledge how to go about it.Well with out knowing the operations in mind, no one will be able to suggest any thing to you, which country u plan to have this setup in etc etc.
Mr.Singh, if you can relax & share your requirements, may be I will eb in a position to give you few tips, so that you can focus and make your own decision.
Regards,
Aezad Ahmad
