Since you'll be home, try and hire a local teen (someone recommended and responsible). I would offer $300 - $350 for the week. Its 7 1/2 hours a day, 30 hours total so $10 an hour would be $300.
I have a local teen who sits for me for date nights etc and during the summer I have her do 9 hours a week for $90 so I can work part time from home.
