Opinions please

Same. My best friend gets Labour for free. But he does a lot of the work himself, and always helps me on days off.
Other good friend never helps,if he does, he actually slows the jib down and effs stuff up.
If hes around,kinda helping its 1/2 rate during business hours.
He makes big bucks flying helicopters, so im not concerned about charging a him a fair rate for work.
Buddy rate and classic cars 50/hr compared to my usual 70.

Dont feel guilty about charging for your time, its worth something.
