I live in Seattle area. Not many here do PG because of the cost but I've heard good things about them from others on this site. Most here do either Baseball Northwest (https://baseballnorthwest.com/) or https://www.pnwregionalbaseball.com/ they are MUCH cheaper so you can keep your cost down. If you timed it right you could do both during the same trip and still have money left over if PG is really $650.00
Based on what they see at the eval you can get an invite to their regional games which have lots of scouts at them. Check their websites to see if any are from our list of target schools.
