landing page/squeeze page software solution

What I need or require: I need software that will create landing pages from multiple templates with various layouts that can be changed easily. The landing page creator would work similar to the [login to view URL] software to create web sites and blogs. Only this would be just for landing pages or squeeze pages and the associated analytics. The landing page would embed either video or audio and include a place for forms from the most popular auto responders, ie. Aweber, GetResponse, Infusionsoft, etc. The forms would be able to pass on data to the autoresponders or have its own autoresponder feature. The landing page software would utilize something like Google Analytics to track all activity associated with the landing page. The software would also allow different elements of the landing page to be split tested. The headline could be split tested against a similar headline. The Audio offer could be split tested against a similar Audio offer and the same would go for video. Reports on activities would need to be easily created from a report interface, showing visits or views vs. submitted forms for conversion ratio. Also a report on click through’s, referring URL’s, keywords used for searching, etc. The software would be able to create multiple pages within a campaign . Information from each page would pass on information from one page to the next using PHP or CGI or whatever language would work best and with the least amount of trouble. The info passed on would come from the forms that are filled out on each page. The flow of information would move from the landing page to a sales page to a thank you page, etc., allowing as many as 4 to 5 page transitions in the sales process. I want this to be available both as a standalone program and server side for my website. Specific expertise/background that I am seeking: Demonstrated ability to create easy to use software that is intuitive for even the least savvy internet marketer. Alos need experience in PHP, CGI or other relevant language for passing information through from one page to the next.
