How much to have an electrician install a new light fixture?

My condo is open concept, the majority of the space being the "great room" in the center of this room is the sole light fixture, a large ceiling fan located above our living room area. To one side of the room is our dining area and there are no over head light fixtures.. I need a ball park estimate of how much it would cost to install a ceiling fixture so when I get estimates I know a little about what I'm talking about. Thanks
