Cat  Sotogrande its a good area  for making your wishes come true. I Have   a few friends (1 from Arizona and 2 others from Uk) who teach at the International School of Sotogrande and live in Estepona, you should try to contact with the school because i know  they are going to hire more teachers ,because some  personal (including two of my friends ) are leaving the job for moving another cities.
Move fast and apply for the job, move  here  and i you dislike Spain, you always can back  Manchester and start a new life  again.
