Setup Marketing plan / roadmap similar to FB Timeline

I'd like to set up (for internal purposes) a marketing plan / roadmap which is set up like the new Facebook timeline. I would need a back end / CMS to enter the items, place them on the time line (left, right, full width(=milestone), etc. On the frontend it should be possible to collapse / expand years/month to see more or less detail (see FB timeline) -> means the timeline is set up dynamically. An action item always consits of Headline, Date (as text), Description (as in the template). A milestone item (full width) consists of the icon (always the same), headline, gray text, blue text (as in the template) a template is attached or go to [login to view URL] Due date: asap Technology: up to you Coprights + Sourcecode is handed over to me after payment
