I have an idea that might help you, because it's something I am doing. I had a similar issue, in that part time jobs in my area did not pay very well. Certainly not enough to justify having to juggle my schedule, figure out how to handle the kids etc.
So a couple of years ago I decided to start a website as an online business. At this point, it practically runs itself. It did take several months for the income to materialize, steadily, but now I am getting checks every month and net income goes into savings or to pay off bills. (You can do whatever you wish with the money, obviously.)
I based my business on a topic I love, and you could choose anything you would like. The key is researching it and setting it up properly.
The best thing is, you can do this at your kitchen table anytime of the day or night.
What I recommend, is getting a copy of the free e-book. Make Your Site Sell by Ken Evoy. I used his methods and a software, and it works great for me.
Just thought you should know about this option.
