Moving to Jacksonville

Hello. I am a Cardiac ICU nurse looking for a good cardiac unit to work in in Jacksonville, F.L. I am also looking for information on how much they pay nurses in the Northern part of FL, decent areas to live, and the cost of living vs nurses pay. I moved last year out of state and made the error of listening to people who were not in the nursing field. Long story short...I love where I work but cant afford to live in the area!! Knowing a head of time would I help me in negotiating salary and determining if I could live in area!!
