S.,
I appreciate your spunk in wanting to work. However, working from home is just that.... WORK. No one will pay you to be home with your children.
Most work from home employees are either self employed (me - we own our own company) or someone who is established with a company because it takes a strong drive, self discipline and work ethic.
There is NO way I could do my job with children under my feet. People who work from home are usually required to have child care. Why? because you are working for someone else and they want 100% of your efforts on the job at hand.
Of course, all the MLM'rs/Direct Sales/Pyramids will contact you to recruit you and you just need to be fully informed of any contracts, expectations, etc... Most all do involve selling, recruiting and some sort of investment.
Think outside the box. I also substitute and I have for 10 yrs. I do this along with running our company. Multiple income streams are very important.. (ex: 1 thing dries up, there is still something there to do and earn money). I am very particular with my subbing and my days are always prebooked.
If you are a certified teacher.... tutor. A certified teacher in our area gets $50 an hour CASH for academics. What about music, other languages, etc. Also, babysitting bring in other children and extra cash. Have a crafty camp at your house one or two days week. What else are you good at.... crafts? Sell things you do not need online for extra cash.
Good luck to you with whatever you find!
