I've seen that a lot of people have suggested getting a band of fellow travelers with similar schedules. From what I've seen, that is not a completely easy task. But if you have one or two people you can depend on to meet you for a run or two, latch on to em. And don't be afraid of the PF.
From my experience, it's better to start your own party recruitment if nothing current meets your criteria. But don't just put the trial info and hit recruit. Be specific about what you want. Is this a learning party? Is it a clear party? Has everyone completed it and your just killing for an FC mate?
If you're going for a clear, make sure it's evident that it is NOT a farm party and jerks aren't permitted/will be kicked. I've explicitly said in PF that I won't tolerate whining because of a wipe. There are more people out there than you think that are casuals and want to clear content without being criticized for their lack of experience.
