You, as the Media Minister, would probably end up organizing the whole operation, but I think that you could probably start by asking if anyone wants to sign on as a reporter for the news room, though we could also just open the presses to anyone who wants to make a news release. It's really up to you how structured you want the paper to be. I'd suggest, though, that you make different "Columns" for different sections of the newspaper to direct people to where they might be interested in writing or reading.
