Help with homework conversation and babysitting

Hi students

My children aged 11,10 and 7 go to a German School.  I need help in babysitting in German language and at the same time I would like a babysitter that can have a conversation or can help in homework. Always after 3 p.m, until 7.30 p.m 2 about twice or 3 times a Week. Please contact me of interested. 

For the elder boy who is turning 12, I am also looking for an English person for 1 hour conversation .

Thank you
