Create special sponsored story for digital transactions site.

Client site has news articles and they want to add a special sponsored article that will show on the news and archive pages with a small graphic that says "sponsored article". Basically, there just needs to be a check box on the existing news story addition page in the admin that will make the article appear. There also needs to be a 30 day timer on the article that will auto remove it as a sponsored story. One kicker is I need this done by tomorrow because the client has sold one of these articles already and needs to get it live. However, this shouldn't take too much time to implement into the site as much of the framework is already there. Site is [login to view URL] Let me know questions. This is the instruction from the client to me... "The project we need done ASAP is to make adjustments to our crm for editorial stories. We are going to have clients purchase an editorial story on our web site. The story will be like our current story page. We need to provide an area for a "sponsored" banner 200X60 above the headlines. We need to make sure that banner, headline appear on our news page, and archive page. We do not want the story to appear on our home page. The story will be posted for 30 days so we need some type of timer or start and end date." Please also mention your hourly rate and how many hours you can work per week. Otherwise bid will be marked spam.
