Market Value

I need information beneficial to work-from-home people and the self-employed. According to the Bureau of Labor, I am a Computer Support Specialist. My fees: $35 1st hour, $25 there after; 34.5 cents per mile for traveling; 20% markup on parts; estimates are the same as consultations and are priced as the hourly rate. Please respond with your pricing, liability, and waivers information. Thank you.
