Babysitting 1-2 days per week for 4.5hours per day

Looking for someone to look after my 1 year old, 1-2 days per week while I work at home. I am flexible with which days but would prefer a Monday (but happy with Monday, Tuesday, Thursday or Friday). I work from home so will be at home with you as well. Looking for help from around 11am - 3:30pm during the day. This would involve feeding lunch and playtime and putting him down for his afternoon nap. If possible some basic cleaning up while he naps (dishes etc.). I have a large Labrador at home so needs to be good with dogs. He is very friendly but will follow you around the house.
