Temporary Housing in Portland-Area

All,

I posted this on the Oregon forum too, but haven't gotten any responses.  Yes, I know I only just posted last night(!), but I realized that there may be people who don't really check the state forums, or people who don't live there that know where I can look!  Please help if you can!

I'm living in Wisconsin currently, but I just got a legal internship in Beaverton for August through December of this year.  So, I'm leaving my husband here in Wisconsin and heading to Portland for next semester!  Now, I need a place to live though!

Unfortunately, the internship is unpaid, so I have a very tight budget.  We're going to have to pay for my husband's housing and food costs in Wisconsin and my costs in Portland all on his income.  I'd prefer to live in either Portland or Beaverton, since I'll be working in Beaverton and going to school at Lewis and Clark Law School for the semester.  However, this is open depending on costs!  I also might be bringing my dog along, but if that proves to be more difficult, I can leave her here in cheese country, too.

Anyway, can anybody direct me to a good place to look for a place to stay for this limited amount of time?  I would REALLY appreciate it! 

Thanks a bunch!
