I highly highly doubt that buddy parts rewired cars for $50.......Buddy parts has closed the workshop, so i doubt they will do it.
I can do it, but my bare minimum is five times the amount you have said. to be honest.....i verge on 10x that amount to wire a 4age
your job would not be that involved. i can do it, but you are still looking round the $300 mark.
Ill tell you something for free, check your battery to make sure it doesnt have a dead cell
