fishing charter boat? how to?

I am moving down to South Carolina this year for college from Ky. Next summer I plan on heading towards the coast for a summer job. I would like to maybe be a deckhand on a fishing boat. I will pretty much settle for anything around boats. Any advice on how I might get a job on a fishing charter? I dont have any experience with saltwater fishing (though I do fish for bass in freshwater a fair amount) but I am trying to get as good of a head start on this as possible. Thanks.
