I have been offered 90-100 per hour over the past few months, for strictly outpatient MSK jobs with some EMG. This is in or around NYC, so this figure might be a little higher as you get away from the coast. These were all for part-time and temporary positions for a new grad, as I will be starting my fellowship in January and have 6 months to work after I graduate in June.
The above figure works out to be roughly 200K per year so not so bad. It does include malpractice but not benefits.
