If you’re a hustler, you might consider trying your hand as an industrial equipment rental broker. In other words, contractors and homeowners can come to you for the best deals on every-thing from backhoes to posthole diggers. From generators to floor buffers. Maintain a current list of rental companies so you’ll be ready when people come to you for help. You can find the best deal and take your cut off the top, OR you can arrange to receive a 10% commission from the equipment rental houses you promote. Considering some rentals are worth hundreds of dollars a day, it could be extremely profitable if you set up a business like this in a large enough market.
If you are a bit techy, then you can build a website to get online services with your referal links to others website. So, whenever people paid to others, you will automatically get your referal comission.
