Hi, I looked into a company at Snohomish - Harvey Field (Can't remember the name of the company but this MIGHT be the phone number: (360) 568-1541). The people seemed nice enough and they do rides to the ATP level, but I decided to go with all-atps because they're a meat market and they get the job done fast. This other school doesn't do that many ATP rides and I got the impression it would cost twice as much.
I drove down to N. Las Vegas ( I assume you're near YVR) but now I think there is a site in California. Their website still says Portland but I don't think its operational. ATP was great and I would recommend going out of your way a bit to get it done there.
Hope this helps,
