Wordpress sales/squeeze page creator to be edited

I have a plugin already done. What I am wanting to do is make it totally visual when making sales pages, squeeze pages, etc. This is how it works right now.. [login to view URL] What I am wanting to do is make this total visual. No list of feature where you have to checkmark and input. Here is how I would like it to be. Step 1. Choose Template > (shows list of templates) Step 2. A pop up will appear to show the new template that you have chosen as it would appear as the page you would be posting. Inside that popped up window, it will show the headline, video, filler content, newsletter box, and any other features that template has. From there, the user can click on any part to edit it or delete it. Along with change colors, add header, add a logo, etc. All the current features that are in the script now must be in the script in the visual mode. I am looking for someone experienced with both wordpress and possible javascript... Not sure what it will take to make this work the way I want it to. If you have any questions, please let me know. If you have worked in the past with other wordpress themes/plugins please post sample work.
