Part time sitter for 3 year old boy

My wife and I have a three-year-old son and a dog. Our son has yet to start school and both of us are working more so we are needing someone that can nanny at least two days a week. My wife would be working from home but she is often in meetings. Our son has a lot of energy so they would need to be able to play with him and take him to the park occasionally as well as prepare some snacks and lunch and we are currently working on potty training
