Custom page template created for Twenty Twelve Wordpress child theme (default wordpress theme) similar to [login to view URL]
Whatever slider is used, as well as the rest of the template, should be responsive and match the default theme.
The slides in the main slider don't need to be pulled from posts with featured images or anything complicated.
A custom post type or whatever is fine. As long as there is an area to select an image, add a summary and link the image to a post.
The lower featured content blocks should be able to be pulled from a predefined category, display the featured image from the post, and the excerpt.
There should be an area to add content between the upper slider, and the bottom blocks, but still fit well if no content has been added..
