Have you asked the scheduler to send you the guidelines? Some schedulers will send guidelines or even sample report. Depends on the scheduler.
I'm a shopper that does the shops i commit to. So I don't want to commit without knowing how involved the shops are. I signed up for a shop in Las Vegas this weekend (I'm licensed for Nevada as well) and I was going to do it. Then I gave it a 2nd thought (after committing) about how much effort and how long it would take me. I felt it wasn't worth it in the end. I reached out to the scheduler and asked them if it's a popular shop and they won't have a problem filling it. I told them I would still do it, if they would have a hard time. The scheduler told me it was popular and just to cancel it, so I did. But I was willing to "take one for the team" since I committed to it, if they were going to have a hard time finding a replacement.
