Couch in or near PDX

I'm pretty hesitant to post this, but maybe one of you guys can help me out. I'm going to PDX for a few days 18-24 and need a place to crash for at least the first three days. My buddy had an out of town emergency, so my first place fell through until my other friend gets back in town. If anyone could lemme crash (18-20th) that'd be awesome. I'll totally pay you for this.
