With my ds, I did a lot of late-late night work.
Ohhh... lucky you. Mine was a telephone sales job, so I had to work office hours. I eventually had to quit because it didn't pay enough for me to hire a babysitter.
Phone calls + kids = disaster

I did two jobs: one answering intakes for a counseling agency (of course my ds would always be TERRIBLE when I was on the phone). And the other was as a portrait photographer (I did shoots on the weekends and editted at night) - but I also concluded that my time was worth more than either of these jobs could pay. I'm extremely fortunate that my "real" job as a psychotherapist allows me to completely create and modify my own schedule.
I do some random free-lance writing, and that is the perfect "after hours" gig.
