Fiona, offer part-time childcare in South wimbledon

I am looking for home childcare help and home help. The childcare is for 2 girls aged 10 & 11 (year 6 and year 7). Hours would be 2.45-7pm on Thursdays and Fridays only.
Type of support required: school run, help kids log-on to their tutoring/homework, prepare a simple meal, help kids get ready for any evening activities/the following day, general house work/cleaning - more hours available for this.
Kids are compliant, capable and fun. I need someone to nudge them along so I focus on work on those Thursday and Friday afternoons. Plus if we can get someone that is happy to do some cleaning as well then there could be additional hours for this.
