WANTED Housekeeper/Nanny

I am looking for a Housekeeper/Nanny for my grandchildren, ages 13 and 17 years. They live in McKinleyville with their father who is a recently divorced commercial fisherman. Because of his occupation, he is gone most days and nights much of December and into January and needs someone to stay with his children, do grocery shopping, light house cleaning, and possibly driving. Most days the children take the bus to and from school. The children are very self sufficient, good children, but need some extra help. When staying over night, a nanny would have her own bedroom. It is a 4 bedroom house. This job would go year round with breaks when my son is home and also when they can stay with me as I live in McKinleyville too. I guess I would describe this job as a year round, part time job!
We would appreciate the help.
