Babysitter Needed

I am looking for a mommy's helper to assist me with my 4-year-old and 9-month-old. I am a new business owner and I just need help with keeping them entertained while I handle business meetings etc. It would be regular hours starting 8/25. My 4-year-old will be starting Pre K that day. I am breastfeeding, but I would like for my children to be able to go and do activities like visiting the library and going to the ark. I just don't have time right now so I need a bit of extra help.
