Looking for helper

We are looking for a helper who can start fairly soon. We are 3 people (me, husband and son), and my son is age 6 - so he needs someone reliable who can look after him after school, and babysit. Other responsibilites are clearning (4 bedroom condo), and laundry. We do our own cooking.

We are from the UK. We offer a salary of $1000, plus an additional food allowance ($200) for the helper to buy their own food. Ideally we would like a helper who can join in late-July or early-August.
