This is accurate. Depending on your situation, clients appreciate getting things done. A very good client of mine doesn't care what I do, as long as I get it done. It might take me three hours to research how a given legacy PHP CMS works just to do a simple code change, but as long as they can come to me with something and be sure I'll have it done at a not-too-great cost, even if it's not my area of expertise, they're happy and I'm happy.
