A cost effective advertising course?

Im trying to find a way to get my foot in the door of advertising, but you need education to get any experience, so I'm told. Being that times are as they are, does anybody know of a full time or part time course, that the industry in Britain/Ireland look favourably on, for beginning a career in copywriting?

And, another question, I've looked at masters courses in advertising and they always say "relevant degree" - is a degree in multimedia a "relevant degree"?....I really want to be a copywriter, and I'll do anything to get there; I just need my foot in the door to figure out the next step! Christ, I dont wanna be washing dishes forever!!!!
