I would love if such service is offered here in this forum, although I highly doubt it, no one has the time and facilities do to this these days in my opinion.
It will be very difficult to make a living doing ONLY arbitrage, and difficult to make both bets at the same time. But you can find opportunities if you make lots of bets over time. For instance, if you bet Panthers +475 to win the Super Bowl or Broncos +600 before the playoffs started, or at even greater odds before or throughout the season you coudl guarantee yourself some cash tonight.
But to do that would involve making good bets back then, which takes effort, not some sort of easy system.
Predicting the Super Bowl finalists is not arbitrage, arbitrage is not about predicting the outcome of a game or a tournament, is more about predicting the odds that will be given and wait and find the arbitrage. The easiest way is to find the arbitrage already there but in my experience it's very hard and the window closes fast if that was the case.
