I ahve known several mothers who worked and homeschooled.
For them, the key was flexible work schedules, depending on other homeschool families for babysitting or a nanny, prepared curriculum and caffeine! (none had families in the area)
One was a dogwalker, one a make up artist, one a party cordinator and another a medical assistant by contract.
I think it is do able. If you can do contract work- that would be great. Also working at home is good- just dont expect to have your child there with you the whole time.
(I ahd one mother write to me, I just couldnt beg her to watch another video anylonger)
I have tried to work part time at night- ebay and contract work- and homeschool and I find it way too hectic, and crazy and stress ridden. (But I ahve 2 children)
I would do a search for single an homeschooling, since singles do have to work most often- and some still choose to homeschool.
Heres a link to a group that used to have some single homeschooling articles-http://www.illinoishouse.org/
If you can scale back and only work part time, that would help the balance a lot.
