I want to do it at four o'clock in the afternoon, because I have to take the children to school.

I can't give you specific job information. I suggest you go to the local recruitment website or social platform to search for relevant information and find a job that suits you. However, please note that if you need to take care of children in your daily work, try to communicate with your employer in advance so as not to affect your work efficiency and the normal operation of your employer.
