Fifty Euro per hour. A border around the Greener receiver is likely to take 8 hours of work. Full coverage is going to be lots more hours.
No denying that cut engraving is the better choice. But the laser work displayed by Boxall and Edmiston is impressive. Especially if it is going to be a simple border on a cheap single barrel.
I've never seen laser engraving that I would pay for. I've seen a lot that I would pay not have at all, so if you have some photos of Boxall and Edmiston that is impressive, I would like to see them if you could post them.
