I do not sharpen for money, although I have a hobbiest curiousity in how sharpening services run and price their services. I found this video today and was impressed with the practical advice Warren Jones shares for local sharpeners.

About half way through I thought "I wonder how sharp the knives are from this national sharpener" then he started talking bout "every 2 weeks". I am guessing that they are doing a quick run over a relatively coarse belt then hone which would certainly need re-doing every 2 weeks. Interesting to see someone look at what they deliver back to the customer.
