Dude, I hope your not in my neck of the woods (no location stated in your profile) because your pricing your services way too low!!!!! You need to charge more than $35/hour for that kind of work if: 1. You're in this business to make money 2. You want the customer to respect you I would factor in labour rate ($40/hour as the absolute minimum) plus equipment. How do you know what to charge for equipment??? Easy.... the tool rental places have done all the figuring for you. Add their rental rates to your labour rate and VOILA' you've got a fair and solid quote. This is the method I use and it works for me--hope this helps.
