Starting over at 35

I’m at a point in life where I am needing a career change. The problem is I do not have any degrees. I spent all of my 20s as a SAHM. Most of my years working have been running a nonprofit which I love but, definitely not for the $$. I have 3 teenagers one of which is only a year away from college. Therefore, I can’t afford and don’t have time for traditional 4 year degrees. Any ideas on where I could turn. Something that won’t be too difficult, expensive, or time consuming. Preferably something that can be done online in the evenings. Open to any and all suggestions please help
