Look at this from a business perspective. Why would you want to build the service twice?
Why don't you do like the morons do here. Early on set a pole out in front of the house and put your meter pan, disconnect and a temp service panel on it. Let them use it for temp power during construction. When you are ready install a panel in the house. When the house is almost completed remove the temp panel out on the pole and run a feeder under ground from the pole disconnect to the panel in the house.
GC gets his temp power and the new homeowner gets a wonderful lawn ornament.

Setting a temp pole, and service, is not a choice, it's a utility requirement, here in jersey. It's also not a business decision.
