Call Center Needed

Looking for a call center, we would like to start with a minimum of 10-15 seats in the call center with a room to grow. Please only respond if your sales reps have American sounding accent otherwise you will be wasting both of our times. We are selling B2B Mobile phone based service and business application on subscription basis. Call centers have to come up with there own leads, we are not going to pay any hourly rate to the call center sales rep but we do offer attractive commission structure to qualified sales representatives.
