Create your own handicapping strategies, build up plenty of proof that they work and then create a website (or have one created for you) that touts your abilities. You’ll have to choose what kind of service you’ll offer (free or paid) and what sports you’ll be focusing on before you start, and you’ll have to put in plenty of legwork to build up the receipts on your capabilities. If you’re good enough to charge for your services, bettors will take note and turn to your handicapping services as a part of their overall strategy.
