Looking for a January swap 2 to 4 weeks in length

I have a large apartment which I share with 2 roommates. My room is a very nicely converted living room. It is literally it's own room. Has a walk in closet, desk and bed. WiFi connection, nice kitchen, great apartment neighbors, very quiet and respectful roommates in a good area of Van Nuys, CA.

I want to go back to the Seattle area to see if I want to move back to Seattle next summer - winter of 2010.

I'm looking for an even swap - no rent paid just a couple of references, couple of phone calls and pictures to see who would be living in my room and with my roommates.
