Babysitter Needed - Full-time / Part-time

I have 2 children, my daughter is 7 and my son is 6 years old. I need help from time to time possibly every other weekend since I work full time throughout the week and never have adequate time to rest, run errands or go to yoga. My children do enjoy playing on their tablets, watching television, playing with their toys, and doing fun art projects from time to time.
