Congratulations on your pricing. Perhaps justify was the wrong word, how about enlighten.
I'm not trying to offend, but do you think that there is a limit to your value? Unless it is significantly different there in Mass. I estimate that you would be charging about $514/hr after material. Does that sound about right? (8 hours work including setup, cleanup, collection; $650 material/permit)
If your service changes take 2 men 8 hours, now that would be a different story.
Without giving the exact number, what range in $/hr is your pricing based on?
Thanks,
Rich
