Depends on how many little kinks he's putting in it. Also depends on how fast he works, if your wire needs a lot of work or a little, and if he already has an idea of what he wants to do or if he's just guessing along the way. It shouldn't take longer for him to make the actual kinks than it does the remove and replace the wire. That's a little more labor intensive and can take about 5-10 minutes for each wire. The whole thing, uninterrupted might last 30-45 minutes.
