Question about cost to rewire a car

Located a retired electrical engineer and racer from our local track who specializes in wiring cars and plumbing nitrous.
He drove over yesterday to look at my car. Gonna have him do it. Will be somewhere between 12-1500 with him supplying everything.
I have hip replacement surgery upcoming here in the next few weeks and me tackling this type of job wasnt in the cards. I am just too big and tall of a guy to be crawling under a dash, etc. Been jumping through hoops and tests, waiting on the VA to finally clear and schedule me for surgery. Gotten so bad its tough just walking i waited WAY too long. Finally awaiting call to get it done
Take the car over week from Thursday, he said couple or three weeks.
May have to have a buddy load it up and bring it back depending on surgery date.
