Get on all of the sub lists that you are qualified for. Many times here in AISD, the best subs can become permenant subs at schools. This will allow you to take jobs when you want, but also be able to stay home when your child is ill.
Also consider working at a "Sylvan" or "Kumon" center. These will also help you get your name out there as a teacher. Depending on what grades and subjects you taught, consider tutoring from your own home.
Our daughter needed math tutors middle school through high school, cause I was hopeless at helping her with any of that advanced stuff. We paid $45 - $60 per hour to her advanced math tutor. The tutor had kids almost every weekday afternoon and evenings going straight to her house.
The other need right now are in home assistance. These are people that help homebound adults that essentially need baby sitters (In home care givers). Most of the caregivers we hired to care for our grandparents prepared simple meals. Made sure medications were taken correctly, visited and documented what our grandparents did all day. We paid at the time $12 - $15 per hour for daytime work and $60. - 75. per over night stay. You will need to be CPR certified.
Consider sales at a Teacher Supply store. Of course I am sure you would be qualified to work at the local school district administration offices, the IRS, City offices. Just apply to all sorts of positions that maybe have nothing to do with teaching, but that you are qualified to do.
