There are a variety of ways to find the job for you; many internet sites will list situations vacant as well as Spanish newspapers and such publications like the Overseas Job Express. Anyone from the UK that becomes resident in Spain, and has obtained an NIE number, and has a valid passport can work in Spain without a permit. There are a whole host of opportunities from modelling to brick-laying available for suitable applicants. See www.4icj.com/es as a starting point, but employment is usually easier to gain once you are residing in Spain.
