I've had older vials take 1 to 1 1/2 days to get going, give it a bit more time. What is the date on your vial?

From White Labs website:

WLP810 San Francisco Lager Yeast
This yeast is used to produce the "California Common" style beer. A unique lager strain which has the ability to ferment up to 65 degrees while retaining lager characteristics. Can also be fermented down to 50 degrees for production of marzens, pilsners and other style lagers.
Attenuation: 65-70%
Flocculation: High
Optimum Fermentation Temperature: 58-65°F
Alcohol Tolerance: Medium-High

Maybe try keeping the starter in a cooler place?

First off, your gravity is too high - you should go 0.5 cup DME to 2 cups water. Or, the easier method (IMO): 100g DME to 1000g water.

Second, starters are for yeast reproduction, not fermentation. So, you shouldn't be seeing fermentation or signs of activity right away, especially on a stir plate. Let them grow.
