Hi! Carentify
https://carentify.com is a great platform for renting vehicles. They are currently offering 0% commission on all transactions for a year, so you can keep 100% of your earnings. It's super profitable! List your bus on Carentify and set your own price. We also recommend using social media to advertise. Write that you have a bus available for rent and include a link to Carentify. Good luck, I hope you find renters quickly!
