Babysitter Needed - Full-time / Part-time

I work from home and have a scheduled virtual training class in which I have to be present in without any child disruptions. I need to have my 8-month-old taken cared of during the training classes schedule which is 10-5, M-F. At 3pm, my other two kids will come home from school who are 6 and 7 years old, though they can occupy themselves. The next class is scheduled for September 2026.
