Looking for a job: Optical technician

My wife and I are considering moving to Menorca. Possibly Mahon or to an area where we can get jobs. I am an optical technician but have done manufacturing before, my wife has done all kinds of administration, customer services, technical support jobs. We don't know Spanish language. Just wanted some advice on location, jobs etc. Prepared to do anything. Any advice would be greatful. Especially any red tape issues. I am British and my wife is Polish.
