Claude Code builds a lead list from free public records, once for my practice and once for a stand-in pool and spa company, and nobody on either list has been contacted. No code to write.

The free kit and the install steps are here: https://www.stephenthorn.com/marketing-kit/. If you haven't written your brief yet, start with /marketing-kit:marketing-brief. find-leads reads it first.
The command
Type /marketing-kit:find-leads, a space, then one plain sentence that says which records, which years and what to leave out. These are the exact sentences I used.
My practice: SBA loan files
/marketing-kit:find-leads Use the SBA loan files I saved in data/ (S23): loans approved in the last 12 months of the files, for businesses in Raleigh, Durham, Chapel Hill, Cary, Apex, Morrisville and Pittsboro that report 2 to 50 jobs supported. Leave out sole proprietors, meaning business type INDIVIDUAL or blank. One lead per business, with its city, industry, jobs supported and approval month. Leave street addresses out. Don't use the internet.It asked whether to keep businesses whose only loan in that window was cancelled. I said no, which left 149 businesses in six cities.
The pool company: Wake County permits
/marketing-kit:find-leads Use the Wake County building permits (S02): Pool-class permits issued October 2014 to October 2018 with status Complete, in-ground pools only. One lead per street address. Add the city and ZIP from the Wake County parcel records (S18). Leave owner names out.That gave 483 households, each with a street, city and ZIP and no names. City of Raleigh and Town of Cary permits aren't in the County's file, so those homes are missing.
Before you run it on your business
S23, S02 and S18 are rows in my sources.md. Yours will have its own rows for your own sources.
Every source needs terms that allow this use. sources.md quotes that sentence, and the kit only uses rows marked approved.
Download big files once before you start, so the filtering happens on your computer.
Read what it says it couldn't test. An OK from the check means the list is complete, not that every lead fits.
Post your company in the community and we'll help you shape your sentence.
