I have already gave you an answer to this. You use SendClientToAll and that sends the message to all the players. Use loop for all players and then if statement. If the skin is correct it SendClientMessage to that player have the correct skin.

    if(isnull(params)) return SendClientMessage(playerid, COLOR_LIGHTBLUE, "Usage: /911 [Message and Location]");
