Maegan, babysitting in Rushden

I'm Maegan, I am 15 years old and I am looking for a babysitting job, whether the odd occasion or part time routine.
I am willing to babysit for any day of the week from after school hours on weekdays.
I would also be willing to give up some of my half terms in order to babysit.
However I have no qualifications in childcare as I only leave school this year, but in the previous years I have looked after my younger sibling since he was 7.
Although, given the chance, I would be able to look after a child from the age of 3/4+ as I am reliable, trustworthy and very organised.
I can help the children with any homework that needs doing (preferably primary school) and any chores that would like to be done I am willing to do. Not only this but if the parent is elsewhere during meal times I would be able to cook for the child/children.
