pagination with custom pages?

[Darksidehackers]

I am setting up a leaderboard system on a custom page and here is a key thing, the main part of the source (to grab database, rows, etc) is all in the page its self (the .php) then I call a main variable through the template in the style manager..

What would be a way to setup a pagination? I'm not to slick with the vBulletin options and prefer to just do it old fashion coding.

Basically heres the leaderboard: http://www.yourgamercards.net/leaderboard.php

Small amount at the moment because I haven't released the trophy card to the public.
