Mental health is a good field to start wiith. Especially with all that is going on. Mental health providers are swamped with clients and they don't always need office staff so many try to bill themselves, but are finding that impossible. We have never done an online flyer so I don't have any example to share. Did you try googling them to see if anything comes up? I would focus on how important it is to have someone making sure all gets paid that is due, and not having someone in the office. But push that you are accessible and I"m not sure if this applies to you, but we have several of us so I advise that even if someone gets sick, your work will get done.
