Honestly I'm not in the mining scene, though I'm going to guess that electric is pretty cheap in the WA/OR area. But from some looking through the internet, heres's what I've found. Can't vouch for any of these services, but this is it.

I found this one - http://bitcoinasichosting.com/ - on reddit, yet again I stress that I cant vouch for them or anything. Seems like they're based in Washington though.
Here's a site for one where you can get quotes from - https://www.quotecolo.com/bitcoin-mining-colocation/portland/ - Seems like they'll get quotes from a couple sites.

Yet again ya know, you're going to have to look into these sites and companies for yourself. But I did abit of the groundwork.
