I suspect in the trade there are only a few who tackle this job but not many. You might do one job well and the next come out looking like a dogs breakfast. Do 50 of them and I bet the last ten are all perfect. It is the learning curve which somebody has to endure and pay for. I had to replace two engraved screws and decided to engrave them myself. I had two screws to finish but used over a dozen screws to practice on first. Had I’d gone directly to the two I needed they would have looked like that dogs breakfast. But with a bit of learning they came out well.
