Swap.com. Like ThredUp, it's an online consignment store. You send in used clothes (women, kids, men's) and kids toys and games, and Swap will sell them for you. Hopefully. They may reject them, in which case you'll either have to pay a fee to get your things back or donate them. But assuming you're sending in clothes and toys that people will want to buy, your odds of selling them should be good. The website says that "sellers, on average, earn about $150 per box they sell on Swap.com when sending in-season, high-quality items." Especially note the words, "high-quality."
If you hook up with a for-hire car parking service (the type hired out for fancy neighborhood parties) you can make some nice cash tips in just a few hours at night and on the weekend, when parties are held. The key here is to do a great job by showing hustle and being super friendly. This was one of the most enjoyable jobs I had during graduate school. Who doesn't like to drive nice cars?
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.
Profit from you photos. If you’re skilled with a camera, you can turn your photos into cash by selling them to stock image sites, such as Shutterstock.com. If the photos you submit are accepted, they can be downloaded by Shutterstock’s subscribers and you can earn anywhere from 25 cents to $120 per image download. Other sites that accept photos from contributors include iStock, Dreamstime and Sqeeqee.
If you have a propensity for writing and you can slay with your prose, consider writing an ebook. While the market has certainly become saturated as of late, books that help teach people about a technical topic still sell extremely well. This is a great source of passive income but does require a large amount of effort at the outset before any money is generated.
Monetize a hobby. While some hobbies actually cost money, others can be transformed into a profitable business venture. Ultimately, it depends on what your hobby is and how talented you are. You could turn your love of photography, for example, into a part-time gig taking family portraits and wedding photos or selling prints on Etsy or at arts fairs.
Next, you’ll need the right tools. You can be as complicated or simple as you want depending on your comfort with audio equipment, but at the minimum you’ll want a microphone and software for recording your voice. Companies like Behringer, Blue, Focusrite, and others sell studio-quality plug-and-play podcast setups that can get you recording today.
Blogging is something that requires patience, persistence and discipline. It may mean writing everyday for over a year before you really start to see any money from it. There are exceptions to the rule, but from my dealings with other bloggers, it seems to be pretty common to spend one or even two years building your blog, your brand and your authority, before making any serious amount of money.
Whether you have a website or are still dreaming up ideas for a blog, you can also look into affiliate marketing. With affiliate marketing, you partner with brands and businesses within the content of your website. If you mention a product or service, you link to that produce or service using a unique affiliate code you received when you signed up for that particular affiliate program. From there, you’ll make money any time someone buys a product or service through your link.
