Simple Website Builder Rotate PHP & CSS

We want to make an easy way to make a site like this: [login to view URL] It should be PHP web admin. Where you just enter ”Header Pic” "page title” block for ”address” ”Domain” URLs to use. Under that we should have Terms – Privacy – About Us – Contact Us. Instead of ”posts” ”likes” ”archive” When it should be able to take snippets like Tumblr do. Take the pic from the URL you enter and some text. From the URL you enter. For the Terms – Privacy – About Us – Contact Us it should just change the name/address/domain in these files. So now the tricky part. We need all the HTML CSS to look unique from each other. SO it should make random CSS names and so on. A lot of changes should be done so it's not possible to see its the same template. (when big G look into HTML code) The template should be plain HTML+CSS. When done it should copy the site into the domain. Also, it should be able to handle HTTPS.
