If there's an event in your neighborhood that will bring in a ton of traffic, you might want to consider renting out your garage space. Say, for example, there are fireworks going on around the corner from you and the street is packed with parked cars already. Those who are late to the show will need a place to park, and you've got the driveway to save them the time so they don't need to trek a mile.
Keep in mind though, you don’t need a website to do sponsored content since you can also get paid if you have a lot of social media followers. My wife has a pretty big Instagram following, and she gets all kinds of sponsorships. Not only does she get paid in cash, but we get a lot of free stuff, too. We’ve received free rugs, free lights, and free carpet cleaners. She only promotes things she loves though, so this strategy works really well for her.
Again, if your blog has a large reader base, then businesses may be interested in paying you to review their services or products. Not only will you get a free trial using whatever these businesses are selling, but you will also get a fee for writing them a review and posting it to your site. Paid reviews (and other paid and sponsored content) can be big money, so advertise this service on your contact page to generate business.
Great ideas although I find writing 20 articles in a day too exhausting. Similarly, I doubt if you can collect aluminum cans in one a day that you can sell for at least $100, unless you will do it with other friends and colleagues. This is a good idea for a fundraiser, though. On the other hand, I would recommend baby/dog sitting or house/yard cleaning.
If you offer freelance services or have a physical services business, then creating a blog is a must. On your blog, you can write about the services you offer and how they will benefit your clients. Importantly you can add a ‘Services’ page, outlining the services you provide, what they include, and any other important information potential clients may need. This is an effective way to promote your services, generate leads, and increase your revenue.

Using a food delivery service can’t necessarily earn you money, but it can help you save you money if you constantly find yourself throwing out half the food you buy. Food delivery services send a box of food every week with new, sometimes unique vegetables, meat, fruit, and so on. If you don’t have time to shop and want simple meal-prep that leads to a good meal, a food subscription service may be perfect for you.
