Like any sales organization the money that you make is proportionate to your ability to write policies/sell (go figure). If you don't follow the call flows/sales processes or flat out refuse to dial out and maintain a decent mindset you will top out at 40K a year no matter the dept.
Essentially the difference between those that make 40K to the top of the sales team at 150K is self discipline and mindset, because well they'll teach you how to sell.
