Here's a practice worksheet on causative structures written on the theme of "Tourism". It covers the active causatives (have somebody do) and the passive causative structures (have something done). The worksheet includes a QR code answer key so you can assign it as homework and your students will check their answers. Also, it includes worksheet A&B versions, which cover the same aspects separately. You can ask your students to check each other's worksheets as both worksheets have similar questions in their set.
