Help with school pick-up

Hi there, our family requires help with picking up our two children from their local school, two to three days a week to then bring home, entertain and help to prepare dinner. I can be flexible with the days between Tues to Thurs. We anticipate this would equate to approximately 2.5 hours each day, totalling up to 7.5 hours her week, beginning as soon as possible, likely 3 August. Our girls are aged 5 (prep) and 7 (grade 1).
