Hospital Internships ... I need help finding one!

Hi there.

I am a high school senior.
I plan on going to a community college to get my Associates of Science in Nursing, then transfer to an L.A. university to complete an accelerated program (RN to MSN).
I will complete my prerequisites this summer to enter the nursing program at the community college, and I would like an internship. I am looking to work at a hospital or clinic while going to school. I am having problems looking for one!

Could you please help me out? I would love to hear your advice.
