Susan, is looking for a child-carer in Kent street

We are seeking an experienced and reliable nanny/housekeeper to help with our 3 kids and home keeping as we work full time. We can offer at least 36 hours a week over tuesday-friday, in term time this would be something like 7-11 and then 3-7, so the middle of the day would be free/unpaid. All kids would be at school so any time during school hours would be spent helping round the house, keeping it clean and tidy, washing, ironing and any ad hoc duties as required.
In school holidays the hours would revert to something like 8.30-6 over the same 4 days. Potential for ad hoc overtime as we work and have a varied schedule, so flexibility is important. Our kids are currently 10, 7 and nearly 4 so going into YRs Reception, 3 and 6 in September. The afternoon stint would be very much about running them around from school, groups, clubs, play dates etc and feeding them dinner/homework/getting ready for bed. We want to find someone committed to the kids, house and the family, reliability is key as we run our own business but also someone fun, kind, organised and happy to muck in where needed and take pride in their care of the kids and the house. We also have a dog (a Vizsla, currently 5 mths old) so they would need to like dogs and be happy to walk/feed/play with her etc.
We have a very busy but happy home and would like to find someone for the long term, as our nannies have been before. Having own car would be best but we could possibly provide a car for the right candidate. We would seek references. Many thanks, :)
