The next business that can help you with making money is reselling. In fact, all the things that apply to the reselling of other goods also go with drones.
You should purchase the popular new models at one price, and lately sell them at a higher price to your customers. All you need to do is find a supplier who sells drones at affordable purchase prices. Take a look at the drones in popular online stores such as Amazon and Ebay.
It looks simple on first sight, but you will have a lot of costs and fees to open and maintain your store. The same goes with online stores, but the fees are a little bit different. So, you must bear that in mind that when thinking of opening a shop for this purpose.
If you already have a store for electric devices, gadgets, computers, and the like, why not add drones in your offer? This is a big advantage because you already have an experience in such a business. On the other hand, you can have a specialized store for drones, where you will sell these UAVs as well as all necessary equipment for them.
Just another tip. if you are thinking at a rental business with drones, forget it. These aerial devices are vulnerable to damage, and you will have problems with your clients.
