I need help on getting online trophies for Red Dead Redemption - PS3 game

Tweet

Hello. Anybody here still playing Red Dead Redemption on the PS3? I am in dire need of help because I am aiming to Platinum this game and the few online trophies that I still need to acquire are the following: Posse Up! Requirements: Create a posse and get the maximum number of members. Slow on the Draw Requirements: Get 10 assists in a single Hideout in a public Free Roam session. Go Team! Requirements: Be on the winning team for four consecutive victories in any team based game in public matches. The Quick and Everyone Else... Requirements: Be the top scoring player in any three consecutive FFA games in public matches. Hence, could anybody here add me on their PSN friends so we can set a game in order to accomplish these trophies? My PSN ID is Snakemaru. Thanks in advance.
