Google And Meta Advertisment For Sports Betting Site

I'm looking to create a comprehensive advertisement strategy for my sports betting site. I'm looking to incorporate Google Ads, Facebook Ads and Meta Ads in my approach, and I actually have all the design elements ready to go. I'm in need of a creative and experienced freelancer who can help me build an effective ad campaign that will target the right audiences and maximize ROI. Due to budget restrictions I am unable to provide a specific number, however I am open to reasonable proposals.
