Advertisers needed to promote podcast

With more states in the U.S. legalizing sports wagering, gambling on NFL football is growing dramatically. Unfortunately, so have con men trying to get people to pay them for their "expertise." But these guys aren't experts at gambling on NFL (if they were they wouldn't need your money). I've been a successful NFL gambler for a decade. I have a podcast where I educate people on betting on NFL football. All my advice & picks are free. I need someone to promote & grow my podcast. I have no idea what platform or how to do this. PLEASE HELP!
