I mean this in the "It's harder to come across this information" sense, not the "LOL ladies, amirite?" sense.
Teaching. Fabric and crafts. Child care (holy is there ever a billion dollars waiting for whoever cracks the code on babysitters). PR work. Marketing/communications. Office managers. Metalworking. Literary fiction. I'm sure you can find something.
But it is harder than simply implementing something that directly helps me.
You know the saying: Men give love to get sex, women give sex to get love. If you can find a way to sell lurv, you will be in very tall cotton.
(Please note that I am female and not "talking trash" about women at all. Thank you.)
