Workflow Issues

I am using wordpress for a bit of a hybrid use. It is a monthly newsletter. WordPress is working great for it so far but I have one main problem regarding workflow.

I get articles that I flow in from a writer. Normally it is added to the site and rss when I hit submit.

I want to delay the launch of the pages until the 1st of the month when our new issue come out. I already know about postdating the timestamp but here is my issue.

I have to have it review by editors and the CEO. I dont mind telling the editors you have to go to the back end and find each article and view it but I dont think that will be an option for the CEO.

So what I want to do is have a working site with the post dated article showing up. Is there like a plugin or an admin level with which I could do this? And not have it live to the public? If I need to elaborate on what I’m trying to do let me know.
