January school holiday cover

Looking for a responsible adult mother's helper to monitor 2 children (11 boy and 12 girl) and manage the house for two days a week (Mondays and Thursday) in the January school holidays when the parents are office-bound. The start and end times can vary and will generally include tidying up, preparing food, cooking dinner and monitoring kids. Need to be strong personality that will not be swayed by my far-too-clever, always-bored and work-every-angle son! This can progress to two afternoons a week in term time if it suits your schedule.
