Maria, nanny in Exeter

Hello, my name is Maria and I'm from Spain and I'm 24 years old.
I arrived to Exeter one month ago to have a new experience and improve my english, so now I'm looking for work in this city where I live.
I´m looking for a full-time (preferable) or part-time carer, including household tasks, doing homework with children and everything.
I would describe myself as a responsible, organised, funny, good sense of humor, careful, and extrovert person who wants to live a new experience while looking after and interacting with children who I love. I dont have any professional experience because I have been bussied looking after my nephew (1 year old) and older cousins (7 and 8 years old), so it is not a "professional" but a experience, that I think is the same.
About games and things I have done with children it depends on the age and sex of the children. With the baby I couldn't play anything, only look after him...but with the others (boys) we used to play football in the park, playstation and computer games at home and watching tv. Besides, before that, we used to do the homework.
I really like children and so I would like to work as a childcarer because for me is not a job, but a funny way to learn english and other things that children can teach you...
