This is feasible and not particularly difficult. Outpatient per hour gigs are now also paying $150 per hour+. ERs are paying $200+. However, I don't know if you are in residency or what, but you'll soon realize doing 50 hours of telepsych on CHMC/prison a week may very well be TOUGHER on people than surgery and will burn you out faster than a wildfire in San Diego.
Furthermore, I don't know of a SINGLE psychiatrist who takes only 2 weeks of vacation a year.
You are a real baller in psychiatry if you work <30 hours a week (in 3 days), make 500k, and take 6-8 weeks of vacations a year. NOW this is NOT possible in surgery (maybe derm), but there's a small fraction of psychiatrists who manage to end up achieving this. On a more feasible note, it's not hard to make 300k, esp. as a solo practitioner (i.e. total net profit vs. W2) and get that lifestyle anywhere. This is why it's extremely difficult to recruit for a facilities job outside of coastal areas for < 300k these days.
