Mikrotik hotspot setup and redirect splash page

I need a solutions for out hotspots that are hosted on Mikrotik Routers, the person must also know how the hotspot engine works on the mikrotik and the redirecting process for the captive portal page. PAP and CHAP is used to authenticate the users session along with passwords on the hosted captive portal page that is hosted on an external web server from the Mikrotik router. This setup should be fairly straight forward and simple to setup if you are familiar with the hotspot on the mikrotiks. knowledge of PHP and HTML is a bonus as well. Thank you!
