2-3 hours is normal, not as easy when done correctly with lettering in correct position, headspace adjusted. I would say you are going to get a quality job from someone that knows what they are doing.
Often, a tad bit has to be taken off the shoulder or a reamer ran in a few .001.
It never hurts to have a quality craftsman look your action and barrel over, often huge issues are discovered in advance.
