Summer Sitter For A 5 And 10 Years Old!

I have two children, one is 5, female and the other is 10, male. The 10-year-old is pretty self sufficient. However, my 5-year-old is very energetic. We can include a pool pass for the right person for over the summer. I would like this person to help my daughter out with learning her number better and alphabet. The schedule won't be consistent. My husband and I work retail so we are off during the week. Four days total we wouldn't need someone for the children but the weekends and two days during the week we would. I am looking for someone who is okay with $50. 00 A DAY to watch them. I know it isn't a lot but this is what we can afford. We have a dog as well. She is loud but she is friendly. The house will be well stocked with snacks and for you and the kids or money left in an envelope for occasional lunches out. My daughter likes playing soccer, swimming, playing outside, arts and crafts, as well as going to the playground. My step son likes gaming, basketball, the playground, football, and swimming as well. My daughter needs help with her letters and numbers. I am looking for someone who is energetic, respectful, responsible, trustworthy, and fun for my kids. We have on street parking and we prefer someone who has their own means of transportation. We have one dog. She is loud and barks a lot but she just wants treats and pats on the head.
