There is a 1-yr fellowship called Neuroimaging, which allows you to stand-alone bill neuroradiology reads as a neurologist. The job market for this is probably small because few people know the possibility of hiring these instead of rads-trained neuroradiologists (who can read all scans, not just brain and PNS MRI/CT - takes 6 yrs total). Maybe only in a private neuro-only group, you could pitch yourself for this position.
6. Excellent job market from what I understand, which is supposedly growing. There's a current shortage of general neurologists, as well as some sub-specialties to a lesser extent. In the south, peds neurologists average 405k/yr because they only exist every few hundred miles in large cities. I've seen ads for gen neuro for 400k, but those were in undesirable locations.
7. Procedures in gen neuro: Not many; lumbar puncture and EMG. Interventional pain (1 yr fellowship): Spinal steroid injections, etc. Neurointerventional (3 yr fellowship): overplayed field from what I've read (people who actually know what they're talking about, feel free to chime in), but this is endovascular neurosurgery and is all procedure. Neurointensivist (2 yr fellowship): probably one of the most badass subspecialties period, and is just as procedural as ICU + ventriculostomies, etc.

Most of the people viewing are aware that salary is a major selection criteria for a job. I recommend checking out AAMC Careers in Medicine and getting a login. Also tells you sweet stats on "Most common diagnoses", "Types of patient encounters by %" (i.e. chronic illness vs. acute illness, relative % of terminal patients, patient ages, etc)
