like how people are tutors for students, can i be a independent nurse for the old people (cant spell old people in meidcal terms, orthopedics?)

anyway can i work like that and be by own boss and make like 40hr?

You can be an independent contractor and yes you'll make a whole lot more.  However, you pay all your own taxes, all of your own insurances and retirement.  You have to be better than everyone else, as does a travel nurse.  You have to prove yourself every single minute of every single shift.  You have problems at one facility, you can find yourself black balled and unemployed
