It has been many years since I last worked in a commercial shop in any capacity. These days I try to stick with my consults/demos/teaching, restoration of tools and equipment, artwork, and the occaissional new glass for someone else's project. Recently, however, I have had some work come in where I not only had to make the glass but also do the install/retrofit and some rewiring on someone's sign. As this appears to potentially be something that will come up again, what is a fair rate for that extra wiring work these days?
