Multipage article module?

Hello All,

I am looking for a multipage article module. It should contain buttons like Next, Previous and Save with the default buttons Submit and Preview. When we click the Next button it should show the form again asking for second page of the article. Lets say if I am writing the third page of the article and if I click previous it should save the current page and should go to the second page of the article.

If we click save button the entire article should be saved only but not be published.

The teaser look should be only the first page of the article (around 250 letters etc).

Please let me know if anyone can develop it for me and how much does it cost for developing. Once I get the cost details I can go into more details.

Thanks
Raj.
