I were to share a simple way to create an advertisement system which allows you to post an advertisement only every 60 seconds.

Place this on top of the script

pawn Code:

new ServerAdvert;
// COLOR
#define COLOR_LIME 0x10F441AA

Now for the actual Command.

pawn Code:

CMD:advertisement(playerid, params[])
{
    new string[128], name[64] ;
        GetPlayerName(playerid, name, sizeof(name));
    if(PlayerInfo[playerid][Level] < 1) return SendClientMessage(playerid, COLOR_GRAY, "You need to be level 2 to advertise!");
    if(sscanf(params, "s[128]", params)) return SendClientMessage(playerid, COLOR_GRAY, "USAGE: /ad(vertisement) [Text]");
    if(ServerAdvert == 1)
    {
        SendClientMessage(playerid, COLOR_RED, "Only one advertisement every 60 seconds!");
    }
    else
    {
        ServerAdvert = 1;
        format(string, sizeof(string), "[Advertisement] %s Contact: %s Ph: %d", params, name(playerid), PlayerInfo[playerid][Phone]);
        SendClientMessageToAll(COLOR_LIME, string);
        SetTimer("AdTimer", 60000, false);
        GivePlayerMoney(playerid, -1000);
    }
    return 1;
}

Now for the timer to limit the amount of advertisements placed.

pawn Code:

public AdTimer()
{
    ServerAdvert = 0;
    return 1;
}

You can use your own function to get the Underscore from the name.
