Eleutheria, childcare in Cambridge

My name is Eleutheria , I am 23 years old and I am from Greece. I have just gratuated of the departement of primary education of the university of Ioannina. When I was at the university I did pactise at primaries schools as a teacher and a lot of times I have watched the teaching. Before gratuation for 5 years I had the oppurtunity to work at an educational camp with groups of smalls children and being responsible for their care and creative activities which gaves me the basic experience I need it and make me realise this is the field I would like to work. Now I live with my fiansee's sister, who has 2 children ( 1 girl who is one years old, and 1 boy who is 5 years old.) and a lot of times, when she works or go out I take care with the children. I am looking for part time or full time childcare. More over I love painting and create crafts with a lot of differents materials as the papper.
I am willing to work very hard, and knowing that I have the ability to work under pessure I am more than sure that I could become very succesfull in my field.
