what about getting your GED first? that will help greatly towards getting you on the road to a good job... having two small children at home limits your options as well because (to me anyway) there is no sense in working if all your money is going to go to childcare.... but perhaps if you got started on your GED, that would be a path to a better job and/or career.
I work part time and fill in extra hours with some bookkeeping from home... it is nice and flexible. with just a couple classes at a local junion college, you can make a pretty decent amount of money... when really a lot of it isn't more complicated than keeping a checkbook. if you have basic organizational skills, it isn't too much more than that.
and just my two cents on those social/sales jobs like mary kay, scrap-booking, etc. it is actually quite difficult to make real money doing those... its one thing if you have a lot of contacts and are very out-going... but really while i realize they are legitimate businesses, they also have weird income schemes and some are just legal pyramid type scams... just be careful and do your homework if you opt for one of those types of businesses.
