Are you considered good-looking? If so, pharmaceutical rep might be a possibility!
Your options as a person with an MD but without a medical license are limited - that is, they aren't much broader than anyone else with some medical knowledge.
However, certainly some areas of lab tech'ing might be possible although more and more labs want people with specialized skills, those which generally aren't taught in medical school.
Insurance companies will hire people to do H & Ps, pretty low level stuff in general.
In some states, you can work as a substitute teacher (say in one of the basic sciences), although you may be required to pass a test (e.g., CBEST).
If you have a local medical school, perhaps working as an anatomy tutor or any kind of tutor (obviously not big bucks if you're working freelance) at any secondary or tertiary school.
There's always research projects.
If you are trained, you can work as a phlebotomist...
essentially there are heaps of jobs out there but I'm not sure of any which require a medical degree.
