Eloise, child care in Chandler's ford

I'm 15 and looking to get some money to buy a new cello. I am rather good at my subjects including music, maths and physics. I play 3 instrements(cello, piano and double bass) and have had little experience in violin, ukulele and clarinet. I look after my 3 cousins a lot and they are 11, 7 and 5 I look after them often over night. I am looking mainly for weekend work (Saturday evenings) and in the summer holidays.
