Help w/ Google Ads Refresh for a Two-Month Campaign

I'm a book ghostwriter and worked with another Google Ads guy two years ago to get a campaign up and running. I appeared in the Wall Street Journal a year ago by pure luck (the reporter clicked on my Google ad!), so I've had more than enough work for the past year to carry me (I can only write two books at once, so I don't need more than 2-3 clients a year). My ads guy has since gone on to bigger and better things / is running accounts for large companies with huge budgets, so I'm looking for someone to do a quick update to my campaign over the next few weeks. Why now? For whatever reason, I booked my first ever clients as a solopreneur between mid/late July and mid-September, and the WSJ article came out in the same period, so I'd like to get my ads back up when it seems like the proverbial fish are biting. I'm also not sure how much AI has changed the landscape of ghostwriting and PPC advertising over the past two years and would like to get a better idea if bringing in clients through ads is even a viable idea in 2027 and beyond. Ghostwriting is a weird profession/industry–a very small subset of the world can afford to hire one, so I want to continue to ensure that they're the only people seeing my ad as much as possible, and beyond that, I'd like to prevent other ghostwriters and people who can't afford my rate from clicking my ad, as they've inevitably comprised most of my ad spend in the past. Given that my previous guy did most of the foundational work up front, I don't think this will take more than a few hours up-front, with a few brief check-ins on my account between now and Oct 1 or so, but if you're interested, please let me know!
