If you are interested in doing focus groups, here's one that is currently qualifying participants. Take the survey (I just did it - it takes 2 minutes) and they'll contact you if you qualify.
"We have a 75/180 minute ($150/$200) in San Francisco or 75 minutes Nationwide ($100) by computer/phone. San Francisco dates are Friday, December 12th and nationally on December 11th." The subject is automobiles. Here's the survey. It's with Fleishman Field Research.
