Hi,
I just read your message, well my dear there could be gazillion of things that are required to set up a call center, with out knowing the call ratio & the working hours or the inbound/outbound, your budget, number of Agents required, etc etc etc.
Incase you are serious and really want to discuss this in detail, then kindly establish your contact details so that we can pursue this properly.
Good Luck & Best Regards,
Aezad Ahmad
