improve ads and site traffic

I'm looking for an experienced freelancer to help me improve my ads and website traffic. First, I'd like to focus on improving my Google Ads. My target audience is a broad range of people between 18-51. My goal is to increase my site traffic between 30-50%. I also want the freelancer to guide me in the changes they've made and explain it to me. If you think you can help me achieve my goals, I'd love to hear from you.
