Looking to relocate back to Spain

Hi all, my name is Tony and my partner is Gabrielle. We both moved from Madrid to Bournemouth about 5 years ago and miss Spain terribly. Gabrielle is a tefl teacher online here and I have a Celta myself, gained whilst living In Madrid. 

At present I am working in the NHS as a medical electronics engineer but have lots of engineering and management experience. We have decided to come over to Girona this coming September and look around the area with a view to relocating. Any advice or tips for living in the area would be gratefully accepted. We both Speak fluent Castellano and have family living in the capital. I am really looking for work in the facilities management sector if possible. Both of us have N. I. E numbers. 

Un cordial saludo. Tony
