Sitter Job in Ewa Beach, Hawaii

I need someone that can care for my 6 year old son once a month on the weekends. Myself and my spouse are in the Army Reserves and are required to work one weekend most months. The dates differ, but sometimes we have the same timeframe. I also have a 12 year old in the house as well, but she is self sufficient. This would be primary care for my 6 year old. We do have a dog, so a pet friendly person is preferred. The hours will vary, but between 5am-5pm. I know it is long days, but again, it is only 1 weekend a month. We need someone by this October. Thank you.
