There are many variables (besides local labor rates) as well that could dramatically affect the cost.
What's at the pole already--would this be a new service entrance, requiring connection to the electric company's grid, or a subpanel fed off an existing service drop/panel? Is the wire run overhead or underground? If underground, who is responsible for the excavation, and is there anything in the way (like a driveway or building)? Are materials included, or only the electrician's labor? What's permitting like in your area?
I'd guess that the costs of excavation/ditching (and filling), assuming an underground run, and probably also the cost of materials will exceed the electrician's labor taken strictly on its own.
