Anyone have any suggestions on collating a "serious blackjack player" mailing list for a marketing campaign related to a blackjack product?
We're looking for a way to collect reliable lists of people who play blackjack seriously, in various market regions (say, for example, in a certain radius around Detroit, or Chicago, or the Northern California gaming-market demographic areas).
I highly doubt that the casinos sell their player data, do they? That would be ideal of course: anyone know of a similar source for substantially the same data?
TIA :)
