I came to Spain, Costa del Sol, 5 years ago. I know how difficult it is finding a job. But as I said in my reply to Beckys, Wemploy are the way to go. They cover nearly all areas of employment and are so helpful, professional and friendly that if they can´t find you a job....no-one will!
All my friends got their jobs through Wemploy including my bloke so have a look at their website www.wemploy.com
P.S. I Seriously recomend learning Spanish to anyone who is looking to move to Spain, finding a job is much easier!

The basic requirement for anyone looking to work legally in Spain is to be an EU citizen! Like many others, I have taken numerous looks at the website - and it appears to be reasonably comprehensive for the Costa del Sol area - but the first and most difficult requirement for people is the lack of EU citizenship - ergo - not having the right to work.

Why not suggest to the folks @ the agency/website that they figure out how to assist non-EU folks in getting legal work? Perhaps they could form an internal pool of specialized works under their certification to legally work - then "sub-let" these folks to local firms. When the required time to request/fill for legal working papers was met, individuals could start the process with everyone's help - and prior profits.

This concept is merely taking the employment agency a step further than it's current status. I should imagine their business (from those wanting to relocate) would double!
