Is self employment possoible for nurses?

In these trying times where there are only a finite number of jobs available, is there any thing nurses can do other than work for someone else? Any entrepreneurial work that also uses their nursing skills?

I am currently beginning an NP program but its along way to completion, and I only work very few hours (all i could get!) and so I was wondering if we should be thinking out of the box?

It would be great if we could brainstorm and see what we come up with!
