Well, I know it's easy, but recentering the worn holes takes a while. Then reaming the hole also takes a while. Actually pusing in the bushing, and broaching it to size is the easy part.
Keep in mind that I've only bushed ONE clock (which is now keeping excellent time, and striking properly).
I think it took me about 3 hours to do 6 bushings in the movement. That includes finding the original centre, marking the plate (with a black marker) around the original hole, recentering the worn hole with a file, reaming, bushing, and broaching the hole (for each one).
I wouldn't ever charge "more than a pro". I believe I'd actually charge much less.
I was quoted 260.00$ CDN for overhauling an Ogee clock movement. The movement was clean (by myself), and only needed a few bushings and new trundles. I thought 260 was absolutely rediculous. This was a price "without seeing the movement" over the phone, from the only known clock repair place within 100 miles. But still.
Then there's the man who cleaned my time and strike wall clock. He did an excellent job, and charged me 100$. That was a much better price, in my mind.
