Gonna have to go with amp-man on that one. As a rule of thumb, 3000 under roof (2500 heated) is about as far as I would try to stretch a 200A service. It would not be a good idea for a house of this size unless all appliances are gas and A/C is geo-thermal. And it does look a little slim on the low voltage side too. I trimmed out a 2500 sqft house today that had 13 phone outlets (Cat5) and 7 coax outlets. Not enough info to give an exact bid but would shoot from the hip and say $10K to $11K with 400 service with discos. No light fixtures included.
