With just a few paint and stencil supplies you could walk the neighborhoods with curbs and solicit your curb number painting services. Obviously, you need to be somewhat handy with a can of spray paint and stencils, otherwise, you might have people coming after you if you mess up their curb. That said, there is a business for this as people are out there making it happen.
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. You could also try doing it in a different neighborhood that might have friendlier people, or do it in a time and place where there's likely to be a lot of people walking around the area (e.g., near a church before the end of a mass).

Any hobby that could potentially make money can be considered a business for tax purposes. File a Schedule C and you can deduct expenses considered "ordinary or necessary," says CPA Neil Schloss of Castle Consulting. If your business is a band, that includes the cost of equipment, practice space, transportation to gigs, even concert tickets and CDs. You're allowed two years of loss with your business, so even if you don't sell any discs, you can still save on taxes.
If you make a mean mojito, invest in a shaker and start mixing for private cocktail and dinner parties—it's the only time someone will ever pay you to get them drunk.

If you have a background in a specific field, you may find there is a demand for writing industry papers in your area of expertise. For example, there are often adverts for doctors, lawyers, nutritionists, and business experts from particular niches, to write white papers on different subject areas. These are well paid jobs that you will need to stake your reputation on, but that can often be worked on from the comfort of your own home.
I recently stumbled on the Trim app and I have to say, this one is a game changer. It’s a simple app that acts as your own personal financial manager. Once you link your bank to the app, Trim analyzes your spending, finds subscriptions you need to cancel, negotiates your Comcast bill, finds you better car insurance, and more. And of course, the app is free! My bet is that it will only take a few days for Trim to put an extra $100 in your pocket. So easy!
