Hello guys, looking for a Bay Area or LA usability test vendor.

[Harry Yi Huang]

We want to do a smartphone(Android & iOS) web browser usage research(interview, focus group, usability test) in San Francisco or LA. Do you have vendors you've worked with and recommend? It will be better if the vendor is familiar with the mobile apps/internet market.

The research details have to be discussed with the vendor cause our draft plan may not be appropriate in SF or LA.

Thanks guys, I really counting on the professionals here!
