I’m a commercial LV contractor but do residential for some of the business owners out of courtesy and let me tell you, residential wiring is the worst. You need to contend with finished ceilings, finished basements with no drop ceilings, wood construction where blocking in the walls is common, and stuff in your way everywhere because it is a living space after all.

As far as price, getting a cable between floors without access to the ceiling usually requires a creative solution. Is your basement ceiling finished because sometimes you can find a pathway (HVAC / plumbing) to get from the basement to the attic. Are you ok with patching holes? Closets are another option if they line up with where the cables need to run to. If I were to ballpark based on past experience, id say 3 hours @ around 100 per hour plus the cat6, jacks, low volt rings and faceplates. Take this with a grain of salt though because every house is different.

Jesus, well done on the duraline installaiton but someone really dropped the ball on the ABF execution. At the very least secure the service loops to the tubes, those fiber drops are begging to get snagged on something.
