Critical Care/ED job for Newer Nurse

I am moving to Nashville, TN in a few weeks. I currently live in Milwaukee, WI. I graduated with my RN in May of this year and have been working as an ICU nurse since graduation (about 4 months). I would like to stay in Critical Care or emergency but I am finding it dificult to locate hospitals that hire new grads or nurses with less than a year of experience for critical care/emergency dept positions. I am BLS and ACLS certified and I am basic and 12-lead EKG certified as well. Although I only have four months of RN exprience I have a year of LPN experience in a Long term Acute Care facility and I also completed an internship on a Cardiovascular Intensive Care Unit prior to getting my RN. I feel like I have a lot of experience and credentials for a relative new grad. Nursing is my second career. I originally got a Bachelors degree in Communication. I felt that going back to school for nursing would give me more job opportunities. This was true in Wisconsin. I received multiple offers when I graduated, but now that I am looking for jobs in Nashville, it seems that they want nurses with years and years of experience. How do they expect the new grads to get trained and take over for the retirees if they won't give us a chance? I'm just so frustrated because I have 3 college degrees and can't find a job! any advice would be greatly appreciated. Thanks!
