Potentially, as long as you don't run out of Lemon Pledge, you're ok on supplies. I think homeowners (or renters) insurance would cover you on liability (I would be unhappy if she broke my washing machine, more unhappy if she broken/stole/etc. my laptop, but really worried if she got hurt and I might be liable, and incredibly worried if she accidentally hurt someone else in the building while I was employing her... but I think a homeowner's policy would cover all of that).
