This is the core of the issue... You don't think it's worth $80/hour to do, however for a skilled machinist in a shop dedicated to tasks like this it is...
They've got to pay Wages, overheads, Rent, Cost of Equipment and Consumables, Superannuation, Taxes, Power, Gas, Advertising and a skinny philo called mikeymike to sweep the floors. They're a business, if that can make a small profit after that they're doing well.
This is why I DIY as many things as I can, only going to specialists if its something that I can't (or it isn't cost effective for me) learn to do myself using my own tools.
