Need a plumber in the Portland OR area

Help! We have a plumbing problem and we are getting some pretty big numbers from the companies we have reached out to.  Can anyone let me know if this sounds legitimate or if we might be able to get some plumbing work done more cheaply (while still being quality work) in the Portland, OR area?  We were quoted $130 for the first half hour and then $130 for each additional hour.  Does this sound like the norm or are these numbers outrageous?
