hi DSA
welcome to TE
I think you need to be patient. I don't know much about Portland bike shops, but here in Seattle, we have shops that sell used stuff.

Do check craig's list, if there is a bike in your size ... it might be worth it.
you're about the same size as I am. It is harder to find bikes our size, but not impossible.
there are some folks from Portland on TE who will eventually see this thread.
