Are there still people not realizing that live betting has built-in protections against these types of schemes? Even if OP has exclusive access to venues and is able to hold a smartphone on his hand at all times ready to press buttons at any moment, the advantage us moot when pretty much every bookie these days will wait like 20 seconds to readjust their odds before accepting a live bet.
So OP is probably looking for idiots to scam. Good luck with your service OP.
Actually I am looking for persons who are familiar with post goal and know where and how to place bets (like myself).
