You could apply for the Stamps Scholarship at University of Oregon and it would cover all tuition and fees, but it is very competitive (only five awarded per year). Otherwise, I agree with @eyemgh that Oregon State is a better bet for your budget. That assumes you are awarded the WUE scholarship that is granted to approximately the top 10% of out-of-state applicants — apply early if interested.
