Need help to change a door handle at home

Hi, I need someone experienced to replace a broken door handle in my house. The current handle is old and doesn't work properly anymore. I have the new handle ready, but I’m not confident doing the installation myself. Ideally, I’d like someone who can come and fix it quickly and neatly. It’s a standard interior door, but I want to make sure it’s done securely. Please bring your own tools if possible. Looking forward to your help!
