captive portal page needed for my system

I have a hotspot solution where hotspot operators and standard internet users sign up at the same page. I need a custom captive portal page similar to an older one I have attached to this project for just Standard Users. they can register, sign in, purchase plans, connect to the internet. I need this to be in a sub directory in my domain [login to view URL] Hotspot Operators will still sign up at got-wifi.com. I need this solution in a reasonable amount of [login to view URL] Project Description: The "announcement" section you see on the captive portal page, those are announcements "HotSpot Operators" can post to their users behind a specific hotspot. This is already built into the system, I just need it to display on the landing page of the captive portal page. The attached page should be for computers, laptops, etc. that are trying to connect to my internet. I will need a page for mobile devices, iphones, android phones, etc. So there has to be a way to determine if device is mobile and force them to the mobile page that is specifically designed for their platform. Keep this in mind when bidding on this project.
