1. You can often dictate discharge summaries for attendings. Most pay $8-10/summary. Some residencies require you do this anyways - but many with the 80 hour work week do not. There are also lots of community doctors without residents everywhere. Get to know some and offer. Likewise, post a note in the docs lounge or wherever. The attendings hate doing this, and after taxes would rather play golf and pay you to do it. You can usually do 5-6/hour. One problem is attendings get suspended when they have too many undone. So sometimes you'll get a call - can you do 500 of these in 3 days... Weekend sucks, but I know people who would pick up $5 K in a weekend...
2. Once you get your license and most require PGY3, but varies by company you can fly on medflights. You need to be in a port of entry - like Miami, LA, Houston, etc. These flights pick up rich sick people from the Carribean. You can make a couple grand for a days work. And go to the beach too. These like surgeons since you can intubate, start lines, etc. Most the time though you just sit. Pt is out in one ICU and you are moving them to another.
3. You can do minor procedures once you have your license. If you have attendings who work at more than one hospital and some hospitals don't have residents, some attendings will pay you to put in lines at night or I&D abscesses or whatever. Kind of depends on the hospitals, but you luck out if your hospital sends you somewhere for one month (Hence you are insured and have privileges!)
4. Find consulting jobs. You can find some under medicine on Craigslist. Many companies need an MD signature to do a trial or to keep animals or whatever. Just be careful that you dont do anything illegal...
