depends on your state's court as to who/when they hire. And not to be the board DB, but clerkships and INTERNSHIPS with courts are much, much different things. It sounds like your talking about a summer internship.
a clerkship with a SSC would be a full-time job for a member of the bar that paid (relatively) nice scratch.
BTW, there's a ton of clerkship (not internship) resources on American Law's website
