If you can find and restore items like furniture and appliances, you can make a substantial amount of money. You can acquire the items on Craigslist, or even at garage sales or estate sales, restore them, and then list them for sale on the site. You may also be able to market certain items on eBay, particularly if they are small, unusual, but high in price.
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.
Creating a video series and selling it as a digital download on your blog, much like an eBook, can be another great seller. A video course, teaching viewers a specific skill or how to achieve a particular activity, may well resonate with your audience. If you are going to go down this route then your videos need to be as professional as possible so you should consider investing in some video and lighting equipment, as well as editing software.
My 10-year-old son brought home a book from our park’s free library box. It was a biology textbook – teachers edition. He said it looked interesting and hey, it was free (having no idea you could sell it). I scanned it in my Amazon seller app and realized it was worth around $150. He was so excited. We listed it for sale for $130 and it sold! Going to tell him, he just made $130!
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. 
Once you have decided what type of product you are going to sell, you need to decide where to sell them. Selling merchandise on Amazon or eBay aren’t your only options. Creating your own eCommerce store is another way to promote your products and generate sales. Once you have decided what you are going to sell, whether it is white labeled products, your own designs, or other people’s merchandise, you can set up an eCommerce website to display these products.
Make money on YouTube. People who love the spotlight and have other online hustles should consider creating their own YouTube channel. If you’re interested — and interesting — you can use the platform to market affiliate products, sell products you create yourself, or receive ad revenue for your informal tutorials or entertaining videos. Once you get the ball rolling, YouTube offers a partner program that can help you monetize your business further.
Every product cannot be defined by its market niche. The niche market is highly specialized, and aiming to survive among the competition from numerous super companies. Even established companies create products for different niches; Hewlett-Packard has all-in-one machines for printing, scanning and faxing targeted for the home office niche, while at the same time having separate machines with one of these functions for big businesses.
