You need to find a particular product or niche to really make this work. Otherwise, you’re met with different shipping costs, always trying to figure out new margins, etc. Don’t try to be everything to everybody. Try to be good in one particular.

You could try advertising more, for example, by putting up signs around the neighborhood, posting about it on social media, or having people you know spread the word.

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.
