Do you enjoy fast food or going into retail shops? Many companies hire mystery shoppers to test the customer service of their stores. A common one is Subway, which hires mystery shoppers to ensure that "Sandwich Artists" are following all the franchise guidelines. If you have time and can travel to different places, this could be a good side hustle.
An Amazon drop shipping business is essentially a middleman between customers who want to purchase products and businesses that sell them. A drop shipper will receive orders from customers, purchase those products from a separate retailer, and then ship those products directly to customers. This helps eliminate some of the costs and time associated with traditional distribution channels.
Entrepreneurs who have the most success are often in love with their business idea. Remember, you’ll be selling it, marketing it, and likely talking about it to everyone you meet. You’ll spend most of your free time developing the business, which means you may spend more time with it than you do with your own family. If you don’t truly love it, you won’t have the fuel and endurance you’ll need to succeed.
I surprisingly get a lot of people asking to detail their car. I never intend to make a business of it, but I love doing it to my cars and people ask me to do it to theirs. All it takes is a cheap orbital buffer (mines a used craftsman) and a shop vac. I normally get easily $100 for a basic wash/wax/vac, or $200 to remove scratches and polish then wax the car.
