Pet/house sitter/dog walker

Hi all! I hope this is allowed; I am not trying to break any group rules 😬

I am trying to find jobs as a pet sitter, dog walker, and/or housesitter. I have searched on FB, nextdoor app and Craigslist for anyone looking for these services. I am not interested in joining a company or website offering these services, as I am medically disabled and would likely need to be paid in cash, as too much extra income could void my disability and I will be unable to afford my health insurance if that happens. I used to provide theses services years ago and get paid in cash, but this was before zelle, cashapp, etc. Any ideas on where to find clients? And how to explain my need for cash only pay?

Long shot, but does anyone on here need these services?
