Alessia, is looking for part time childcare - SW1X London

I am looking for someone who can pick up my 10-year-old son from St. Boniface in school in Tooting, take him home and stay with him until I am back from the office (roughly around 6:30 pm) on Wednesdays. On Thursdays, I would need someone who can pick him up around 4 pm (I can take him to Tooting Broadway Station), take him to Clapham South at his martial arts class, take him home, give him dinner and stay with him until roughly 9 pm. I am not sure yet about the martial class as he's not sure he wants to carry on but definitely, I would need someone from 6:30 pm to 9 pm. I would need someone starting from the 11th of September.
