You don't need people to contact you. If you want sure matches, just find a blog where these kind of matches are published for free like https://justgreenup.blogspot.com/ - what I can see, they just take the matches where the odds crashes, e.g. Orenburg - Akron Togliatti tomorrow where the odds on hometeam to win with more than one goal are going from 2 to 1.50 - so no need to pay for this kind of info, everyone can see big money on the small market, the point is that you have to get in, in time - so if you are the first one reading their posts, you can still get good odds
