So we were planning on having our good friend be our officiant (he was going to get ordained online). But now, it looks like he might not be able to attend our wedding!

So now we're 3 months out, and in need of an officiant.
I'm presbyterian, so I wouldn't mind having a presbyterian, or maybe unitarian universalist minister, but FI is not Christian, so we'd need someone who would be willing to do a multi-faith ceremony (or at least minimally so).
Would also be open to having a judge, etc.
Any recommendations?
