Gigabit Pro service availability in western WA

I would like to get started with the process of turning up Gigabit Pro (2Gbps symmetrical) service at my single family home in western WA. I am a tech pro and understand all of the implications. Any Comcast employee out there that can help? It has been very difficult trying to get anybody at Comcast to understand fiber service availability.

I am currently a Comcast Gigabit (coax) customer.
