Build a sports betting arbitrage software

The software would have to work like this: 1. Visit the webpage of a specific bookmaker and spot matches with 0% rake in the moneyline market (one match offered per day) 2. Compare the odds of the first bookmaker to those of 3 other bookmakers. 3. Estimate if an arbitrage opportunity comes up 4. Notify me (via email/ on-screen) as soon as an arbitrage opportunity occurs
