I already had ads running before the advanced verification was required. They gave a 2 month heads-up that ads would no longer continue to run after November 1st, 2017 for unverified locksmiths and plumbers.
At this point I don't think any ads would work for new/old accounts without being verified. That includes plumbing.
I was running the ads for myself, but even if I weren't, legitimate locksmiths are all 50+ year old white guys set in their ways, very little chance of them letting me run ads/collecting a % off of my work.
