Don't know the name of the place, but there is someone selling
firewood on Highway 99, between 168th and 128th in Everett/Lynwood (maybe at about 160th?) They're on the east side of the road, and you can see the wood they've split stacked up on the property.
They've been there for at least 5 years.
I suggest driving down there, taking a look at what they've got (hard wood vs. softer woods, how long the wood has been seasoned etc.) and you can talk with them about rates and delivery.
Unfortunately, we converted our fireplaces to gas a few years back so I don't have any experience with any of the vendors. But I'd start there because you can meet the people in person, look at the wood they are selling and have more to go on than just a voice on a phone.
