You can update this as you negotiate and finalize the scope of the project.
Make this a confidential project
Make this project private. It stays off the public jobs board and out of search. Only people you share the link with can view it (they'll need a free Holler account).
Still needs a project title, at least one service, a content niche, a budget above $0, a project description, and a timeline.
