Build a lead list from public records

I sell [service] to [type of business, e.g. insurance agencies / law firms /
HVAC companies] in [state or area]. Help me build a list of every one of them
from public, official records.

1. List the official public sources that publish these businesses: licensing
   boards, state bar or insurance department lookups, open-data portals,
   secretary of state records. For each one give: the name, the exact page,
   who publishes it, the fields it includes (name, licence number, status,
   address, phone, email, website, licence date), whether a bulk download
   exists, how often it updates, and its terms of use. If you are not sure a
   source exists, write NOT VERIFIED. Do not invent web addresses.
2. Write the filter: which status values to keep (active only), which licence
   types match my buyer, and the area filter.
3. Write the cleaning rules: duplicates (same phone or same licence number),
   missing contact details, addresses outside my area, businesses that look
   closed.
4. Add three columns I will fill in myself: website; "already advertises"
   (from the Meta Ad Library, with the start date of their oldest active ad);
   and one fact I checked, for the first message.
5. List the rules for contacting businesses from this list in my country:
   consent for texts and calls, email rules, opt-outs. Mark it as general
   guidance, not legal advice.

Do not give me a count. I will get the count by downloading the file.
