Where our listings come from
Every business on ExpertMarketplace comes from a public state license list or set up its own page with us. Here’s each source, what it covers and when we last checked it.

How we check licenses
For licensed trades we match each business to its record on the state board’s public list and show the license number, type and expiry date, with the month we checked it. When a member uploads an insurance certificate, we read it and show the insurer and end date. The Verified mark comes off on its own if either one lapses.
Pay figures
The “How much does it cost?” sections use the U.S. Bureau of Labor Statistics wage survey (May 2025) for each metro area, matched to the closest occupation, which we always name. They show what workers in a trade earn, not a quote.
Members and other listings
Members can be contacted through ExpertMarketplace and show first. Other listings are businesses that are listed but not in the EM network yet. Paying for ads never changes the order of member listings.
