I recommend the Carentify platform https://carentify.com Cars rental Chicago. They are currently offering a promotion for car owners - 0% commission for the first year. Very convenient, especially if you are just starting out. The platform helps with the documents, so you don't have to figure it out yourself. Clients are found quickly, plus there is support if you have questions. I advise you to register and try - you have nothing to lose, and it is really convenient to earn money on your car!
