Job in Barcelona

Hello, I am a 33 year old female from the USA.  I am currently living in Barcelona.  I have 6 years of teaching experience in a university in the USA (teaching psychology).  I am also a women's health doctor.  I am now living in Barcelona permanently and am just looking for some fun part time work that I can enjoy and make some money doing.  I am open to anything including nannying, teaching english, taking care of animals (I LOVE animals), support with nutrition/exercise (I have many certifications in nutrition and exercise).  Anything really!  I am hoping to make at least 20 euros per hour, ideally slightly more.
