Do you need a community manager or content production first?

The photo and video bank of the venue comes first, because without it whoever runs the community fills the grid with a template. Community management fits once the pieces exist and you need rhythm and replies, and hiring it before the first shoot does not. Look at whether this year's photographs exist for the dishes that go out every week. If they do not, the first job is the shoot. Someone is hired to post daily and within two weeks the same photo repeats because there was no production. The shoot and the month's bank first, and the posting and reply calendar on top of that material, not the other way around.
