It sounds high to me too, but I had a local place quote me close to $200 to do two 3.5 ft oil lines for me.I thought that was crazy. My ends, their crimps, so much hose at $ per inch and labor at $ per hr. Granted I spec'd quality hose.
I agree it is high, but I guess I'll bite the bullet and have them do it. I've seen videos and it looks to be an easy and rather quick process. They charge $90.00 per hour for labor and I assume the hoses are lined with rare earth materials.
