For those who can't get to the grocery store or who struggle with preparing fresh, healthy meals that taste good too, turn your kitchen prowess and passion into a passive income source that gives back to the community.

The online business I Do Now I Don't started from what might at first seem like a niche concern: Its founder experienced a failed engagement and tried selling the $10,000 ring back to his jeweler, who only offered $3,500. It's now an e-commerce site that sells gently used jewelry and other accessories. Typically, the company offers the seller more money and offers the buyer a lower price than a jewelry store, eliminating the middleman – and driving sellers' earning potential right alongside the business's – as much as possible.

It's no surprise that after a night of drinking, most people don't want to clean their home. That's where Hangover Helpers comes in.

Since opening, the company has estimated it has kept 597,640 plastic straws, 851,950 plastic bags and 490,856 nonrecyclable cups out of landfills.

Manhattan's Spread takes everyone's love for free food in the office and adds a genius marketing strategy for local restaurants. This company helps new and under-the-radar restaurants build their customer bases by matching businesses in the area to food they're likely to enjoy, and delivering free samples right to those businesses' doors. After the samples are delivered, the recipient group fills out a survey about the food. Then Spread schedules the group for another surprise sample delivery.

Each delivery comes with coupons and a card featuring details about the restaurant. That way, you can learn more about where your food came from and reorder from the restaurant if you and your employees enjoyed the meal.

Every day, technology makes it more possible for employees and entrepreneurs to run their businesses and get the job done from anywhere, which means businesses don't necessarily have to invest in renting or buying office space.

WeWork provides office space for the officeless, with flexible, month-to-month membership options for individual freelancers and large companies. Freelancers who prefer to work outside of their homes can have a more reliable workspace than a local coffee shop, and companies and other teams can have a place to collaborate and hold meetings and events.

Do you ever find yourself wishing you could go back to school, or maybe even teach a course in a subject you're skilled in? Skillshare, founded in 2011, makes both of these things possible. The company allows experts to teach online courses on a subject they choose via short videos while students can watch classes at their own pace and use the community to get feedback. Students can take classes offline via smartphones and tablets if they'd like to learn on the go.

Unlike college or graduate school, with their high tuition rates, Skillshare costs $99 per year. Half of that fee goes to pay the company's teachers, so if you're an expert in something, it's a great way to make some extra money. And if you're looking to learn new skills or just brush up on old talents you can use to earn a passive side income, Skillshare allows you to do so right from home.

Skillshare also gives back: According to the company's website, for every annual membership purchased, Skillshare donates a membership to a student through the company's scholarship program.

While bigger might be better for some, Minimus takes a different approach. Operating for more than a decade, the online company offers more than 2,500 different individually packaged products, including travel-size toiletries and individual servings of various food items – everything from chips to Tabasco sauce.

The company was founded after the Shraters, the family behind it, noticed how much product they were wasting at the end of a trip to New Hampshire. Today, the company takes up two large warehouses in Los Angeles and employs dozens of workers. In addition to the individual items, Minimus sells premade kits specially designed for different uses, such as baby and family kits, outdoor kits, first-aid kits, and military care packages.

For some events, the typical green and cramped portable toilet just won't do. To address this seemingly niche need, ElizaJ has come up with one of the more innovative business ideas out there, to much success. It rents out high-quality, clean and attractive portable restrooms for any outdoor event – perfect for hosting something a little more formal.

Each of ElizaJ's individual restrooms includes fresh flowers, designer soaps and lotions, name-brand paper products, wicker waste baskets, air fresheners, and fresh water. One of the options, The Powder Room, can accommodate events of up to 350 people, and is designed to rival restrooms in the finest restaurants and department stores. ElizaJ has also launched a franchising model to give other entrepreneurs the opportunity to run their own portable restroom operations.
