Laser repair trade pricing?

I have a customer that will be doing trade work using our laser
welder. Trying to get her some on what a fair price structure would be
for laser repairs for the trade. I know that David Geller has retail
pricing in his guide book, but we are looking for a wholesale/trade
price guideline.

Thanks in advance, Tim A2Z Metalsmith Supply Inc 5151 S Federal Blvd
