Everything here comes out of accounts we run: our own detailing company in Broward, and client work in South Florida. The guides exist because a client asked the question first, and because the answer we found was different from the one the industry repeats.
Two rules for what gets published. Numbers come from accounts we have access to and permission to show, which is why the detailed ones are about LuxeWash, the detailing company Digital Anchor owns. And when something did not work, it goes in the article: the five Broward cities we shut off, the keywords paused at $150 a conversion, the tracking that failed silently for weeks. A guide without a failure in it is usually marketing.
If you run a service business in Broward County and want the short version for your trade, the industry pages have it, with prices.
