I also used to hate outbound calls, and oh gosh, cold calling was even worse. (Mobile phone sales to massive organisations).

Not sure who you initially speak to when you dial, but I really found it helpful to be REALLY nice to the 'gatekeeper' (aka secretary, receptionist, PA) until I got to the person who I really needed to speak to. That worked well for me as then that gatekeeper would be putting in a good word for me in the event I needed to call back or make further contact.

The only other advice I have is to really believe that you have a great product / service to offer, and when you do get to speak to the 'decision maker' keep to the point and be succinct as they're usually really busy and don't want to be on the phone too long. So steering anything towards a 'time saving' / 'increasing efficiency' tag was usually a win for me.

Keep us posted how you go hun! Good luck!
