To be a consultant, you need to have expertise in something so you can market yourself as an advisor to others looking to work in that area. Perhaps you managed several large warehouses in your career with a drugstore company, you did all the marketing for many years for a large shoe manufacturer or you set up a chain of beauty supply shops or take-out restaurants. You can use this experience to help others do similar things without making the same mistakes that you made along the way.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
Take advantage of the growing delivery trend and sign up for a service like Instacart, UberEats, Postmates or Amazon Flex. You get paid per delivery, in most cases, and can even earn tips. A car isn’t always required — Postmates lets you use a bike, scooter or your own two feet to make deliveries — but a background check almost always is part of the deal. Learn more about how to get started with Amazon Flex, UberEats and Instacart.
Not only will this multiply the money you’re bringing in in a serious way, but it protects you against any sudden changes in the market or in your business. Remember that old saying about putting all your eggs in one basket? A few hours a week committed to just one or two of the following opportunities will put you in a much stronger position to be financially safe and independent.
Accommodate Multiple Forms of Payment: Many deal-seekers carry cash, but you want to accommodate every potential buyer. So, in the days leading up to the event, consider purchasing a point-of-sale system that can accept credit cards. Square is a popular and relatively cost-effective option: it doesn’t cost anything upfront and bundles credit card processing fees into its own per-transaction fees, resulting in a net expense of 2.75% for most transactions (net of $97.25 for every $100 charged). This is a small price to pay to capture the ever-growing cashless consumer demographic. On the day before the sale, visit the bank and grab $100 in small bills and coin rolls to ensure you’ll have enough change for buyers who do prefer cash.
Another option that isn’t quite cash back but is along the same lines of “make money by saving money” — the Honey Chrome extension. Whenever you head to your cart to check out, Honey searches for online coupon codes or better deals from different retailers. That means no more wasted time Googling “[insert store name] coupon code” just to come up empty-handed. Honey does all the legwork for you!
We're all guilty of spending too much time on Facebook, Twitter, or Pinterest sometimes, so why not get paid to put your expertise to work as a side business idea? Lots of companies, especially startups or those in retail and travel—even influencers have heavy social media presences and are constantly in need of people to help build their brands online. You can find these types of opportunities on sites like Flexjobs and CareerBuilder and most employers on these websites are conditioned to working with people who operate these services as their side business idea. Over time as you grow in your ability to leverage various social channels, you can add more service offerings like running high-return Facebook Ad campaigns or hosting lucrative sweepstakes competitions for the brands you want to work with.
This is another area where large, often tech-focused, companies are consistently looking to hire remote workers. Like with customer service agents, tech support specialists are focused on answering customer questions and solving their problems. However, tech support is more specialized, so it does require a little knowledge about working with the product.
I have 3 VAs. I couldn’t function without them. It doesn’t matter how big or how small a business is, they all need help running their day-to-day administrative tasks. Virtual assistants perform a variety of tasks that a traditional assistant or secretary would normally do, including making travel arrangements, paying bills, or managing expense reimbursements. I use them to upload content, optimize images, brief writers etc.
Maybe you're not very good with computers, or don't want to sit behind a desk? Well, here's a side business idea that has more of a physical component to it. If you also like working with others, then becoming an on-call mover will likely fit the bill. When someone's moving, they always need a helping hand (or three). You can provide that service and make some cash with this side business idea. Whether it's helping someone who's moving apartments or linking up with a local mover who needs an extra set of hands, working as a mover can be a pretty good gig.
Another way to utilize your talent and business skills is to run corporate workshops online. Businesses are always looking for unique ways to help educate their workforce, and if you can package your talents into a day or half-day long session, you can sell that to companies all over the world to make money online. Start by building a portfolio and then reaching out on LinkedIn to influencers at relevant companies to see if they would be interested in you teaching their team.
Fashion, style, and grooming continue to be a lucrative side business idea that can be done in your hours outside of work. If you know how to mend clothes, then you have a growing market of budget-conscious and/or personalization-obsessed customers. Entrepreneur says you need around two thousand dollars to start a decent side business idea in this niche but there’s no harm in starting smaller and growing from there, as long as you can make magic with needle and thread.
Considering that you have a finite amount of time, passive income should make up a large part of your work. If you're serious about generating any semblance of income online, then passive income should be one of your sole goals and ambitions. Why? Wouldn't you prefer to do the work one time and get paid repeatedly as opposed to relying on your time to generate that income? Invest the time at the front-end so that you can reap the benefits on the back-end. This means putting in a bit of sweat equity and not getting paid today. Rather, you'll get paid somewhere down the road. And you'll continue getting paid whether you keep building that passive income stream or you stop.
