Here in Valencia, in the villages and towns, there is a big call for internet and telephone systems as a lot of houses and urbanisations are STILL without telephone lines.
Telefonica is an incredible company, they need a damn good shaking up, you never know they might be crying out for a trained employee!
There are lots of services being offered here in the city, vodafone, tele2, jazztel, ono, orange just to name a few.
Spanish is very important in this area too, well its what you would expect really as we are in spain no?
