It's like "top pay" and "best rates" it's subjective or what their opinion is on the matter.
I guess if you only have a pickup and minimum amount of tools maybe 50/HR would be enough
Personally if it's not 75/ hr or better for a contractor.it's not enough,for most of our trades. All dependant to me on how equipment and insurance is required. C
On units the ability to make that hourly rate without killing yourself to do it, and without crazy insurance that takes all your money
