I live in a retirement community. I used to have the local hospice and meals on wheels programs let me know when someone was living "in poor conditions" and could not afford or was not able to pay for service. I did those jobs free.
I didn't get any promotional and very little referral work from it, so FINANCIALLY it wasn't a move to make, but it made me feel good to help out people who were often alone and uncared for in their final months.
Take care,
Lisa
