Looking for SAHM for childcare

We are looking for a SAHM to watch our two year old at our house. You would be in by 9 out by 1 and work three, four or five days a week, depending on your availability. Pay negotiable.
My son is usually at daycare, but the doctor put him on a treatment where he can't be around too many kids because his immune system is weakened. He is fun kid and loves to go outside, play in the park and go in the pool. We both work from home and we aren't getting much work done these days.
We figured the time would be perfect for a SAHM looking to work in a stress free environment where you took care of just one child on a part time basis. We would hope to have a semi-consistent schedule from you with no expectation of hours during school breaks when our other kids our home to play with our little guy.
