WordPress Theme and Widgets

I want a wordpress theme designed that users will use to customize a sales letter, squeeze page, or product sales page with. I would like the user to create a new page - then select a header (this 1st version will have 8-10 headers) Each page will have customizable options, like a Headline where they can select a font, font size, and font color, then a place to insert and format the body text (same as a regular wp page editor), a product Image (user will insert a few styles of product images), a video (user will insert a url to a video and set display size), then a Sub-Headline where they select the font, font size and color, Then a List Box, we will need to have several styles of listbox (one with a dotted border and a soft yellow background, one with a bulleted list, one with a checkmark list, etc) They have to be able to create a reply to form that will email them, so we will need a few form templates, and lastly, we need the ability to apply a Button, (basically select from a number of Order Now, Buy Now, Add to Cart buttons), then a Footer, where we will have several styles of footers. See the image attached for examples of the types of pages I want this theme to be able to create. Also a similar product can be found here. [login to view URL] and another example can be found here [login to view URL] If you watch the videos you will see how it works. I do not want as many features as this product. I am looking for a theme that is well designed, easy to use, that I can provide to users with a number of pre-made pages (pages that were created using this tool), and the ability to add and customize their own pages using the tools included. I would like to see some examples of your WP Design work when you biid.
