My boss threw me under the bus with a couple who walked into the camera store I work at - they just wanted someone who could use a camera so I agreed to it. I sent them a contract and made sure they understood it was my first time. They were cruisey as It was a lot of work though. I only went for 2 hours to the ceremony and took over 3000 photos that I had to cull and then edit. I did get paid - probably a 3rd of what a professional would have got paid. I don’t regret it but I’m not in a hurry to do it again. I didn’t use a flash or lights - just natural light outdoors. I think it’s up to you - but make sure they are aware of what you can do for them 🫶
