Go to your local library and ask the librarian for the book on internships
in their reference section - I don't remember the title (something like
'Internships'), but it's a huge book and most libraries have it.  It lists
internships by field, and then by state.  All you have to do then is call
or write to the ones you're interested in.
Happy Hunting!
