What are some side jobs or VERY SMALL businesses one can do on top of a full time job?

By side jobs I don’t mean normal part time jobs at mcdonalds or whatever.I am already working 3 part time jobs and I have no other normal hours that I can work a part time job. But I was thinking about newspaper delivery or something like that. Our town doesn’t have any new delivery positions open but can you think of any other similar jobs?

As far as business ideas, something with a pretty simple start up. I might buy a gumball machine, or a few, to set up at local businesses. Any other business things like that, which I could det up fairly simply, cheaply. I don’t mean get rich quick. I just mean something like vending, where I could do the set up, and earn at least a little without constant time feeding into it.

Thanks in advance!
