Casual Home Help Needed

I am looking for occasional help in the home is the afternoons. We have 4 children aged 9, 7, 5 and 3. I am a stay at home parent but occasionally need an extra pair of hands, to help with afterschool activity drop offs/collections, homework meal prep etc. This wouldn't be guaranteed hours every week it is more of a casual arrangement for the times when we are very busy. If you think this would suit you I would be very happy to hear from you.
