Working parents and parents on a budget:how can I make money without pushing it too far with work?

I am not sure if you are old enough (you may have to be 18+) but I know quite of few ladies make excellent money in sales. My Aunt sells Mary Kay, another Aunt sells Avon, a family friend sells Premiere Jewelry. The Aunts are SAHMs and do it for extra income and the family friend does it as her income (and makes out quite nicely) (:
