Have a knack for staying organized? If you're a jack of all trades, you should consider working as a virtual assistant as a side business idea. You can find great gigs on Elance, Indeed, or Upwork. It can be an awesome way to rub shoulders with some very important people, build up your professional network, develop in-demand new skills (like creating GIFs and VR videos), grow your side business idea and you'll have the added perk of being able to start this as a home based business idea. Becoming a virtual assistant can be a particularly great side business idea if you're hoping to travel the world while making money online as a digital nomad.
Define your product or service. Starting an online business gives you the benefit of having access to millions of customers, but you also have a lot more competition. No matter what you're trying to sell, you can bet that hundreds more online retailers have a similar idea. What differentiates your product from other similar products? To help your product stand apart from the rest, you'll need to find a niche.
Market your talents to building contractors. People purchasing new homes can often be overwhelmed with the choices and possibilities in home decorating. Design some questionnaires for each major element and each major room in the house. Find out how the homeowner will use the home--are there children? Pets? Does the woman of the house wear high heels? Do the home's residents neglect to remove shoes? How will each room be used? Where might task lighting and ambient lighting be most appropriate?
