Chances on getting in????

I'm 25 and have been a 911 EMS dispatcher for 4 years...and figure now is as good as time as ever to go ahead and start on my career. I feel I am mature enough now and will be focused enough to achieve goals I set. I ultimately plan to become a CRNA. My problem is that I graduated high school with a 3.5 gpa...if I remember correctly my ACT was 24. Then College happened, I went to UNLV in Las Vegas and fell apart from there. My parents were paying out of pocket for my schooling and ended up pulling me out, but not before I was actually put on academic suspension. I was young and dumb and look back now and want to kick myself in the butt everytime I think about it. My question now is...have I dug too deep a hole for me to get into a BSN program? I have been looking at various ones here in the atlanta area. Emory, Ga State, and Medical College of Georgia in Savannah. Am I doing a lot of wishful thinking? Could I maybe take classes at one of the schools as a non degree seeking student and just get my GPA up and apply for the program when it's sufficent? Any help is appreciated.
