Cna

I'm 17 years old and I'm positive that nursing is the career choice for me. I volunteer at a hospital once a week and just this past week, I was involved in a nursing camp that was a really great experience. I learned the basics on measuring medicine and injecting in the arm and thigh, how to insert a Foley cathader, taking vitals, assessment skills, and other things, including shadowing nurses at various departments of the hospital. Two of the students involved in this camp are CNA's who got certified through their school. My school doesn't offer that kind of program, so I've been looking at community colleges to see where I can get certified, the only problem is it costs $700 dollars and that's not including the test cost. So.. I was wondering if anyone knew of any places that would teach for free or for a cheaper cost. Also, is there an age requirement to work as a CNA, I won't be turning 18 till June 2009. I live in Northwest Indiana, so the closer the classes are the better. Thank you so much for your help, and if there's anything else you could add on college and which ones you recommend would be greatly appreciated ! :)
