I've got a SaaS system that generates a small physical newsletter that I've been running for the past 3 years. Averaging consistent $600 / month profit w/ no marketing. I've always intended to grow it (and think $2k / mo profit would be easy to achieve), but haven't put in the marketing effort as I've been busy with other businesses. It takes about 1 day a month of work, but that could easily be outsourced. Open to selling for 1x to 2x ARR, since I've been neglecting it a bit. Email for more details.
