Build a website -- 2

Generally whenever user types in any non-existing URL, server generates "404 Page Not Found" error. I want a PHP script to tap this non-existing URL and generate a page on the fly with the contents based on some keywords in the URL if those keywords are found in the separate definition file. So, project consists of only 2 files : 1) Main PHP file and 2) Keyword Definition file (and of course there will be external CSS and JS files if required) I want a simple PHP script which will generate a page on the fly with one top banner image, one side banner image and some text matter besides the side banner image, and some hundreds of links (automatically generated) at the bottom of the page. All these content generation will be based on the keywords in the URL. =============================== Sample Example of What I am Looking For: =============================== Open this URL in your browser: [login to view URL] (This URL physically does NOT exist on the domain [login to view URL] but still when you type it in browser, it generates a page with top header, then top image banner, side image banner, some page contents beside the side image banner, and at the bottom of the page in the section "Our other products and services :" hundreds of links which are clickable which again opens some non existing page. And finally footer of the page) That's all ! I want exactly same to be done in PHP script. Nothing more. Note: ==== 1) We need complete well documented (easy to understand) source code of the project. 2) No proprietary code or component should be used. 3) Project should run on shared web hosting environment on Linux as well as Windows server. 4) Generated webpage should equally good in all major browsers - IE, FF, Chrome, Safari (and should be responsive). Quote your best time and cost for this. Thanks.
