Welcome! Here are some tips for using this forum.
James, My reply was not meant as an insult. If after 24 years you need advice on YOUR costs of doing business, do yourself a favor and learn them. My point is how would you expect anyone to know how to price a job if you the " business owner" doesn't. Knowing your costs, in my opinion is Business 101. Simply put James, stop being an employee and become a business owner. YOU SHOULD NOT HAVE TO CARRY A TOOLBOX AFTER 24 YEARS. It's not that I couldn't carry your toolbox, I don't have to. That's the difference.
P.S. The 6 employees in my firm earn @75K per year, have 3-4 weeks paid vacation,10 paid holidays and have family health insurance.
