Help me with Internet Marketing

I own a website where we promote all of the biggest online casino/betting brands in the UK, and am looking for an email list of real players. Emails can be of players in the following categories: Bingo Casino Poker Sports Betting All emails must be of recent/ active users, at least 2013 onwards, who are based in the United Kingdom. I want quality more than quantity, and would rather 10K+ genuine emails to 1M inactive useless emails. A sample of 1K emails is required before i agree to accept any bids.
