Short-term, Part-time (3 Days) Care For 2 Year Old

I'm looking for someone to stay with my 2-year-old son, in my home, for 3 days a week. The days will alternate every other week, so one week would be Monday-Wednesday and the next week would be Tuesday-Thursday. Hours would be 8:00-4:45 some days or 8:30-4:45. I am a teacher, so there are some breaks that I wouldn't need care, but those weeks would be communicated from the start. Position would be from March-mid June. My son is very sweet and fun. He loves music, books, playing, and talking!
