Junior Nursing Student - Summer Internship

Hi everyone!
I am currently a junior and will be graduating from my university's nursing program in April 2013. I am currently employed as a care provider for a young woman with special needs and as a home health aide at a nursing home. It is difficult for me to work often during the school year so my hours are limited. I am not getting as much job experience as other students in my class and during my clinical I feel that this shows. I am VERY interested in a summer internship as a nurse extern or something along those lines and was wondering where I should be looking to find one. I would prefer for it to be in Michigan.
Thank you!
