You got a really good score, that should put you at the top of list of candidates to call. That said, they'll only call up people when they're about to embark on an operation - and there are several. I actually waited more than 6 months before my first stint, which was address canvassing - verification of addresses - using a cool hand-held computer, walking from place to place. Now I am doing another operation, which is following up non-responses from the questionnaire sent last month - involves interviewing people. Timing wise, it works out with my subbing because typically, sub gigs are in the morning, while the best time to interview people during weekdays is in the late afternoon when they're home.
