Best thing you can do is run your own cable snd just have them hook up both ends, more than half the price us them crawling around and drilling holes in 2x4s. Lots of online tools to estimate your cable gauge to length.

I estimated my line with a 60 amp pull because I foresee future cars wanting more amps…4AWG, was $200 just for the cable but most of the cost is labor so why not future proof it.

Also check with your state, my state offered a tax credit 50% of the cost of my install.
