Telemarketing/Appointment Closing

I'm looking to hire an experienced telemarketer with a proven ability to make sales. My ideal candidate needs to have experience closing and actually selling something and know how to sell. I have a social media marketing agency for which I have appointments already booked for with the owners so they can get to know more about our services, I want someone to attend these appointments through calling at the time they have been set and close the decision maker or dental office owner. Note, that this is not a cold calling job, someone has already done the cold calls and booked a few appointments, now I need someone to call these booked appointments and close them on our social media marketing services. I already have a dialer for you to use if you are overseas. You NEED to be fluent in english and cannot have a thick accent. We value our customer/prospect service a lot and hold it in high demand. Payment will be decided on the meeting you have with me. Thanks, and look forward to working with the ideal candidate!
