If all you have to do is put in some breakers and run the wire, it's probably something you could easily learn about on youtube or just google searching. As long as you have the open slots in the breaker panel.
Basically it's turning off the panel, popping in 2 30AMP 240V breakers and running the correct size wire to an L6-30R receptacle. Then buy a PDU and that will give you some room for 3-4 miners usually. (Mine draw 5-5.5 amps so I can get 4 on a line and not violate the 80% rule).
You could always call an electrician and explain what you want to do and see if they can give you an estimate at least on the phone.
Also if it is continuous you really should only do 80% of the rating. This would be 1920 watts for 120v on a 20 amp circuit.
I would only run one 8 x 1080TI rig on this setup. I use 225-250w per 1080TI.
You really should run 240v with this kind of draw.
Below is my 125amp panel dedicated to mining. Yes, I did it all myself.
I undervolt them and runs roughly 180ish watt each.. so that's why I ran 3 psu instead of 2...
Problem of rewiring is that my electric panel is @ basement and I have to run some seriously wires to first floor laundry room (which I'm using it for mining)..it's a weird NYC townhouse set up I know.....
On top of this....I never ran electric wires before. I mean I'm pretty handy (I can build a honda engine with my eyes closed) but I don't want to be on the news
And hiring an electrician is going to cost heck lot more money.
sigh....maybe I should youtube and do it myself
