Not sure why PPF is so expensive in the Seattle area, but that just seems to be the case with most installers charging around $2000+ for a full front kit (wouldn't bother with half hood kits). CarToys I've seen do it cheaper but of the few I've seen, they don't seem to do a great job.
Check out Darkside in Bothell. He's done PPF and tint on a few of my cars over the years and does a great job and doesn't charge as much as some other places, but still north of $1000.
