Looking for a 30+ hr a week babysitter for the mornings

Hi my name is Rylie. I'm 23 years old and have a 12 year old step daughter named Mya. She only spends the weekends with us. I have a 6 year old son named Noah and 4 year old daughter, Rylin and an 8 month old daughter, Zoey. Noah is in kindergarten until 2:15. Rylin will starting pre school in the fall. I would need a Babysitter from 9am-2pm mostly Monday through Friday. I'm a full time student and my husband owns his own company so he is very busy. I would just need a Babysitter when I have classes.
