Advertising/Marketing summer internship on the west coast?

I live and go to college on the east coast with a major in English, but my dream is to break into the advertising/marketing industry. I don’t care what I do (creative dept/account planning/sales/etc), I just want to learn as much as I can about the industry.

What are tips for procuring a summer internship on the west coast (SF, Seatlle, Portland, etc)? I have a resume with minimal experience in my field, and know how to write a good cover letter – anything else I should do? Maybe some of you guys have experiences you’d like to share about how you got your first summer internship? (That didn’t involve an already established contact)

I really just want to know what would give me an “edge” in all of this. Thanks.
