Looking For Weekly Heroic Strike Help PS3

Hello, I am new to this group. I have been playing solo today trying to collect 3 strange coins. No luck no matter what I do or how many engrams I have collected today; usually I can collect 3 in a day. I am looking to do the Weekly Heroic strike so I can get my coins; tried to do it solo but I'm just not good enough to do this one. I am a level 28 hunter with a PS3 and no headset. I can hold my own in a strike, and have done all of them on levels 24 or 26 with 2 people. So I don't care if we go all the way to 30 if you want. I'm not great at shooters but I am familiar with the Hellmouth strike and have done it many times. My screen name is MrSilex. Be advised that I have never played with anyone so I'm not really even sure how the invites work. Thanks!
