Need a place to stay in Portland from April 30th to May 15 to 18th, Attending UBI

I will be attending United Bicycle Institute in Portland from April 30th to May 18th. Initially, I was going to stay in a hostel for the few weeks that I was there, but figured it couldn't hurt to post a thread here to see if anyone has a unused bedroom or a couch. I'm more than willing to pay rent for the few weeks. I would be stoked to stay with a local during my stay to show me around the city or do some skiing/biking. Let me know....Thanks
