You shouldn't have a problem getting a job (if you turn out to be an ok guy on top of that...). I would advice you to reconsider training in Spain though. There are some scary rumors going around about schools down there.
Now I'm not much for the rumor base and you may know more about this then me allready - just trying to give a heads up.
You may also gain some valuable contacts if you train in the UK.
Do you have FAA certificates then? If so - throw out any ideas you may have that JAA theory is a walk in the park because you have extensive flying experience. I'm currently converting my certificates now and let me tell you - FAA flying and JAA theory are like night and day.
