Hi,
If you have not already done so, then have a look at www.britishcouncil.org which gives information about teaching English as a student as part of your degree or if you are more advanced as a qualified teacher.
Failing that, most Spanish cities have lots of language schools offering their services to Spanish citizens. Although You might have to travel into Murcia or Alicante to tap into this arena. Once you get established you will attract businees from recommendation.
Villamartin area has a high number of native British speakers, so you might be able to engage your skills as a translator assisting with things like Applying for N.I.E numbers, Driver or Vehicle licensing or registration transfers, Hospital / Medical related or everyday items that involve Spanish officialdom.
It can be very much a " land on the ground and follow your nose " experience.
Your ability to communicate in the native language will be your true advantage.
Good luck
