I thought it would be best to introduce you to the ways of selling introverted by simply listening in to a conversation I had with Billy.  Billy sells, of all things, used Fire Trucks!  Not only that, but he has a whole team and organization built around this cottage industry.   But there's a lot of personalities involved, just like anywhere else.  Listen and enjoy.
