Recently I checked a CNC milling machine and found the CRT monitor faulty. Tomorrow I will install a new LCD monitor as replacement.
How much should I charge the customer? USD100 per hour?
Thanks for your feedback.
I'd definitely go for $1500 flat rate for 5 hours, $275US/hr after that.
Also, multiply your cost for the replacement monitor by a factor of 4. That's a reasonable markup.
Don't forget to charge door-to-door for your travel time, plus mileage and per diem.
