adamhill - Not my own, but I have a neighbor in a coffee shop who cooks well. There is a shop in Saltillo and several flooded houses. Also comes to you for cleaning vehicles.

granolca - Know a guy who had one but he went bankrupt. He was trying to emulate this commercial exterior cleaning service here https://brightexteriorcleaning.com/. However, his financial management and distribution skills really sucked. I told him he should have gone to business school or at least some courses on how to run a business but he ignored me. I have also found a great article/post on Indie Hackers, its called 2020 in review: $0 to $100K+ MRR for our Cleaning SaaS/Ecommerce. If you want to read up on starting such a business this is a must-read. Amazing article and success story.
