Sitter Job in Lafayette, Indiana

I am currently working a midnight shift and my fiancé works a 12 hr rotating day shift. I am trying to get my children enrolled in Head Start. If that works they start the 6th of Sept. I am looking for someone Mon, Tues & Friday one week and wed & thur the next. Until Sept 6th, and Fridays (maybe Saturdays) every other week to continue after that. I get off at 6am, I sleep till the kids wake up and I usually put them down for a nap in the afternoon, but the days my fiancé works I only sleep when they sleep. I had a neighborhood teenage girl come over after nap time until he got home but than schools starting. They have never been watched outside of my home except for summer camp programs. I am looking for them to socialize and child care for them so I can sleep, maybe 5 or 6 hours a day, two and three days a week.
