I'm looking to add ethernet ports to our home, and can't get any ballpark quotes without having an electrician come to the house charging a $50 service fee to evaluate. I would do this if I had any idea what to expect ahead of time, but don't want to have 3-4 electricians come out to compare quotes and end up paying $150 in service fees before even having any work done.

The ISP modem is on the main level, no current ethernet is wired in the home. I want to add an ethernet port on the second floor, so would need the ethernet wired through the wall likely into the attic and back to the wall of the second floor.

Any ideas on a ballpark for pricing here? I have no idea what to expect so wasn't sure if I'm looking at $200 or $800 or somewhere outside that range.
