I didn't put the whole title in the heading. It goes like this: 101 Weird Ways to Make Money: Cricket Farming, Repossessing Cars, and Other Jobs with Big Upside and Not Much Competition by Steve Gillman.
According to the introduction, this author has tried many of the jobs in this book or ones similar to them. Did you know that there is a viable market for selling maggots? Maybe you have a clean gene. How about diaper service or crime scene clean-up?
Want a green business? There's information on solar-roasted coffee, recycling electronic waste, and old oil-tank removal.
Are you computer savvy? Maybe you can sell virtual real estate in game worlds or buy and sell domain names.
It seems like there is something possible for almost anyone in this book. I noted a couple I thought were especially relevant to my skills, but not maggot farming. lol
