i posted this on the budget board awhile ago but if anyone didn't see it here goes:
With my first dd, I applied at a daycare part time. I considered this almost a work from home job because we went in for a couple hours a day... I helped make and serve lunches and covered some breaks for people while my daughter got a play group out of it. I would leave after a couple hours with projects to do at home for the teachers (lesson plans, art projects, etc.)
Second dd, I worked for a office scheduling appointments. They had a seperate line that people could call and leave their phone number. I would get the tape in the morning, go home, play the calls and return everyones call and schedule their appt.
I also had a job delivering papers. It was a weekly newspaper, so I only had to work one day and could drive my daughter around we me. I actually made really good money doing that.
My friend works for a company that allows her to work from home full time. She does computer work and basically gets emailed information, which she types, researches, and returns.
I would suggest calling a temp agency or placement agency and see if they could suggest something. Also their are a lot of "mom friendly" offices that do their best to help out with creative jobs. If your have any special talent (writing, photography, etc.) you could try to find a way to incorporate that with working.
