Its probably not that easy, a lot of the costs only happen as an average damage to the fleet and property of drivers with X amount of experience. And of course there are so many variables that the answer your looking for cannot be had.
The two biggest things are if you are 24 or older, and if you have a clean record or not. Other than that insurance companies are all different prices. You just have to check around. For a new O/O, Progressive will be about your only option though most likely.
