For a couple of longer term customers I charge $145/hr.

I'm working a full time gig now and haven't taken on any additional work in ages, but depending on contract length I would start at $170 and up.

As I've seen posted here and elsewhere if you're experienced and charge less than yearly salary/2080 * 3 you are giving money back.

(My wife worked as a buyer at one of the national labs and had to purchase contractors, should used to have to tell them what to ask for because more often than not it would be too low for her to quote them out.)
