PLS HELP! advertising for GarrysMod

i looking for an “advertising Addon”.

What does that mean.
This plugin makes a “advertising Box” in the Screen center or in the right bottom conor, when a player is spectation or dead (Gamemode: TTT)
The Box show a Text dokument or a webpage. I think Webpage is the best.

The “advertising Box” can show more than one advertising. But not at once. Random one of many.
The “advertising Box” comes Randomly after a random time intervall

The “advertising Box’” is not to Big!
