Colo in Vancouver is seriously expensive. We had a suite at Harbour Centre up until around 2003 or so... we still have a half-rack there with a handful of machines but pay way more than your budget for it.

Besides, with the American Peso falling against the Canadian Pound every day you would probably get more love with your Loonie south of the Border.

Closer to 49degrees North would be FiberCloud in Bellingham.
(they also have a facility in Everett)

Moving south you next hit NetRiver Ex-REI store & AT&T's Ex-Hardware Store Colo in Lynnwood.

Downtown Seattle has colo places at 1000 Denny (L3 & XO), Fisher Plaza (INAP & AdHost), and more (but smaller) colos in the Westin than you can shake a Cisco switch at. Switch & Data has a facility just west of the Westin too. Somebody about 4 years ago turned an old USWest POP into a colo downtown whose name escapes me. I remember some guys who built a colo in the Olympic Tower @ 3rd & Pine many years ago, but can not for the life of me recall their name either. I have no idea if those two are still there.

If you took 405 south from Lynnwood you would find a few facilities on the eastside too, Worldlink in Bothell, and Isomedia in Bellevue. There used to be a few big .com facilities in Eastgate (405/90 area... Verio, HostPro, etc) but I think they all evaporated in the bust. Colo.com built an 80,000sq' facility in Canyon Park and were about two weeks away from opening when they went Tango Uniform. Some folks were considering opening it at one point... I wonder if they ever did.

Past downtown & Boeing Field, where the parking is free and the facilities big you'll find the Intergate.Seattle datacenter campus. There you'll find Savvis (ex-C&W, Ex-Exodus facility) Abovenet, HopOne/Superb, InterNAP's shiny new digs, Fortress Colocation, and ourselves (see sig).

Follow the Duwamish river upstream past the shocking density of strip malls in Tukwila and you'll find Qwest's fresh-out-of-mothballs CyberCenter over behind the Claim Jumper. Somewhere on the left bank in the endless maze of tilt-up warehouses theoretically is an MCI colo facility but I've only heard tale, never seen it myself.

If you like the smell of pulp and arsenic, like to see aging rockers play the Emerald Queen Casino and/or a domed stadium with a wooden roof, you can go further down I-5 to Tacoma where you'll find Optic Fusion.

If ex Nuke Plants are your thing, some um... people ...have decided to take the old WPPS-Satsop plant down past Olympia and make it an office-park-colo-thing.

That, in a nutshell is the Western Washington colocation market, right off the top of my head, no Googling. I probably missed a few, but they'll chime in and correct any errors I just made. Obviously I've been in this business way too long. Googling and some phone calls/emails should get you some pricing.
