Hi B.,
I'm looking for the same thing. I'll let you know if I find anything worthwhile.
If you are good at organization, I've heard that professional organizers make good money and can schedule their work on their own time. Of course, you'd still have to have someone watch the kids while you were organizing someone else, but it's something I've been looking into. I've heard they can make $50/up.
The other thing I've thought about was house staging - where you work with a real estate agent to arrange and/or decorate a house for sell to help it sell more quickly. If you have a good eye for home decor and design, that might be good. With that one there is the possibility of taking your children with you, since most of the time the homes needing to be staged are unoccupied.
Those are my thoughts. Hope they help.
Good luck in your search.
P.
