Immediate start: Childcare needed for 3 children in Newcastle under-Lyme.

I am looking for a babysitter or childminder in the ST5 area who will care for my children as and when needed in my own home long term for at least the next 2 years. They are 2 girls and 1 boy, ages are 10, 7 and 3 respectively. They are happy everyday kids with no dietary or special needs. I would like someone who is available on some weekend evenings or day too. The hours vary and will start off on an ad-hoc basis and will progress to full time once I go back to the office later in the year. The person will also be required to do a few house chores in-between. This will suit someone who is looking for side earnings. Thank you.
