It's$32 for 1.25 hrs. Weekend reservations can be tough to get. As for outdoor courts, there are some new ones at Jefferson park that look nice. The only other I have played is at a park near my house, but they are not that good.
Cool man. I live on the south side of Seattle. Where/ when are you available to play? What is your skill level? I am not sure what NTRP rankings mean. I may not be at your level, I would say I am slightly better than beginner/amateur level.
