Mike, I agree with some of the others posters.......$25 per hour may be great money.............but only if you consider seasonality, your direct and indirect job costs as well as how much profit you'd like to have.
START by knowing what a job will cost you........the selling price is determined by know the above as well as what kind of a profit you must have to feed your face, your company and your family.
THE GOING RATE, whatever that may be could KILL you.
Don't know how far you are from Atlanta but will be taking a swing through GA, SC, NC and Virginia starting this month with my "Money Maker Workshops". Check my site under events if this is of interest.
Hope this helps.
