$150-180 +Tax (if Prime) to DIY
You need a spool of cat 5e/6, 6 Keystone jacks, 3+ Faceplates, some single and double gang brackets and a few cheap tools.

The brackets are what goes into the dry wall so the face plates have something to screw into.
Single / Double Gang is the size of the bracket.
Single gand = the size of a box for 1 outlet.
Double Gang = The size of a box for 2 outlets (side by side)

Note* You are going to be under the house or in the attic. The work sucks but its way worse going in there for a 2nd time to run 1 extra wire... do yourself a favor... if you are running 1 length to a room.... run 2.

[EXTRA]
This is not necessary but super helpful for drilling through studs you cants see. Also keeps you from cutting more holes in the drywall than necessary. If you are done drilling holes, sell it on Craigslist for @ afterwards.

I will always recommend wired connection for anything that doesn't move such as desktop PCs and most of the equipment in modern home entertainment systems.

You can get 100s of feet of ethernet for pretty cheap as well as a crimper and ends. Depending on how much they've opened up the walls you may not benefit much from doing it at the same time the wiring is being done because you don't want to run low voltage in the same bay(space between two studs) as power lines.

Per 1000ft, the cabling shouldn't even be that much if you did it yourself.

That seems a bit excessive to me in terms of per run based on the cabling alone as the work boxes, face plates and jacks don't even cost that much. Yeah I understand the contractor needs to make money. Is the contractor putting in a patch panel as well?

Amazon has good deals on high quality cables. I'm using the 35' version.

I happen to be on the same end of the house they stuffed the router, but I dont have wifi built into my desktop.

If 200' still isn't enough, you can buy cat6 cable in bulk. Just need to install the ends.

I got 1000ft of Cat6 off Amazon with some crimpers and other stuff for ~80 shipped free with Prime I'd look into that. It seems cheap but I get great speeds on my home network with ~20 drops and a lot of them pass over electric runs and lights.
