Google Ads Master for Search, PMAX, YouTube for Legal Lead Gen

We are a reputable Legal Marketing Agency. We drive traffic for ourselves and internal clients. At any moment we would have dozens of 'litigations' and campaigns that we are running high scale plaintiff acquisition for. We would like to add a team player who is 100% dedicated and accountable for their performance. I personally started my career buying adwords traffic. We want someone to independently guide and scale our campaigns into a massive 6-7 figure per month marketing effort. We need someone who is self disciplined with a deep obsession to detail and performance. Please tell me how you have been successful with scaling lead gen, primarily with youtube. Do you have legal lead gen experience? Please tell me why you would be a great addition to the team and we should trust you with our google ads campaigns. Thanks!
