You can start your own business renting out your tools, as a mobile service. You can reach more customers, if you are willing to travel! You can start from as little as one rental item, and ad things to your list, as you get them! You could make more money, if you offer to let them rent it, for longer periods of time. You can have a more special, and personalized service, where you come over to the customer’s home, and show them how to use the equipment, and pick it back up from them later, when they are done.
You could offer all kinds of rental items. Just drive around, and just about every town, has a rental store around it. You can see some of the things they rent out, like paint sprayers, stump grinders, and items like that. You could expand into party rentals, like cotton candy, popcorn, and snow cone machines. You could offer lots of party items. You could include on your flier, that you offer personal service, and helpful tips.
You could send out business cards and fliers, to local real estate agents, landscapers, and nurseries, that you have mobile tools for rent. These are the people, that usually have either clients working on their homes, or landscapers that come across certain jobs, they could do, but they might not have every tool to do it with, and now they know, they can get it from you, and you can get more customers that way!
You could use a trailer that you pull behind your car or truck, and start small, and buy things you would like to rent out, and have fun with it! You could advertise to car lots, for all your party items, like the popcorn machine, cotton candy, hot dog, fun jump, and so on, because they will want a lot of your items, when they are doing sales, and other businesses as well!
