Another way to help calculate the price is: If you were doing this full time, how much take-home post-tax money would you need? If you need $80,000/yr post-taxes then $80/hr will get you pretty close after self employment, federal (income, fica, medicare, ss, etc), and state taxes. Granted, this calculates how much you'd NEED to charge to have X income, but it does kind of help with the process of starting to determine a ballpark figure.
