I don't know where in the USA, Bellvue is; although, it sounds like Chicago area.
I am a retired plumber and just want to pass along that there are some plumbers who can replace the sewer without digging up the yard, the landscaping and driveway. They use a cable, a sharp metal head that destroys the old pipe, and new flexible plastic pipe that comes in big rolls; so you get a one piece sewer line and no chance for roots getting in it. You may be able to find one of them in the Yellow Pages.
I would suspect the wiring in a home that old is outdated and insufficient; requiring a complete rewire from the pole to the receptacle. In this case I would get at least 3 bids and check their references.
