Some churches don’t have volunteers for their music. A talented pianist, guitar player, etc. can make pretty good money doing this on the weekends. Most churches offer tryouts on occasion. This idea is pretty easy to get started in that you just need to reach out to your worship pastor or someone in that ministry and let them know you have the talent and some experience. Don’t be shy!
Great list. I have another to add that’s almost as easy to do as going for a walk! Provide a litter cleanup service outside commercial properties for property management companies. The work is done on foot using simple hand tools. I started this service in 1981 as a side hustle and quickly grew it into a lucrative full-time business that I still operate. I share my experience with others in my book, Cleanlots, as well as offer free support.
