Phlebotomist does not make much money at all, I would stay away from that one. It is good for people who need to work, and purse more college in the meantime, but not for a longterm career:
Average wage is 26,710 to $38,950 per year
Our friend who was a college grad and couldn't find work, J. finished dental hygienist school. It's 2 years and makes pretty good money.
X ray techs can make decent money.
