Exterior door install cost... from scratch?

There is no existing door or window so the t-111 and drywall will need to be cut, framed with header, re-drywalled, textured, trimmed and painted, and so on. I'm sure there is one wire that will have to be moved but plumbing and gas is under the house so it won't be a problem. It will also need some wood steps outside that will also need some concrete work for the landing, but those will be pretty straight forward. Any ideas on what this might run on labor from start to finish? I was going to do it myself but really don't have the time to deal with it right now. I am in Southern California... that might help with your estimation.
