I try to be reasonable on my prices. I don't always charge for drawing time when I do my own CAD work. Most people charge $1 per minute per laser time. I just throw a reasonable price out there. For the most detailed photographs converted to laser... Engraving time would take about 60-70 minutes. My jigsaw puzzles I added to the store recently, those will take around 2-3 hours from start to finish on just a 150x100mm wood card, just to give you an idea of what goes into this work. Eventually ill upgrade to a better laser that can process things faster.
