I'm not a doctor, nor have I played one on TV.

Yeah, but you’d have to live in Dickson, which isn’t great.

It’s near the interstate and only about 45 min outside of Nashville. $300/hr is a lot of money.

Assuming you get 5 12-hour shifts per month, that’s only $216k per year. Sure, you have a lot of time off, but you can make much more as a doctor, depending on what kind of specialty, of course. Maybe OP can tell us what kind of doctor he isn’t.
24 hour shifts
Certainly possible. I haven’t bothered looking into what types of shifts are typical for doctors in hospitals, but $430k is certainly more attractive.
