Have you checked the real milk website? A lot of raw dairies also have eggs- we visit one in Enumclaw (probably a bit too far south for you!). www.realmilk.com has lisitings.
www.eatwild.com also has listings of farms with eggs, many of them pastured.
You can also get them from SeaBreeze Farm, which is located on Vashon Island. They are $$, but delicious! You can buy from SeaBreeze at the Sunday market in Ballard.
