Torque Wrench Calibration Service - Northwest?

My torque wrench is going on 25-Years strong now. I want to get it re-calibrated. I live in the Pacific Northwest area. Wondering if there is a good service close by or at least on the west side of the nation. Send me your suggestions and costs. Thanks!

Brand: ATD Tools
Model: 101

Have you checked out recalibration vids on youtube? I did mine and got it within about 2-3 ft lbs. Worked out great for the engine rebuild.
