Start ninety days out. Use the first month to build a named target list of twenty-five to forty accounts across three tiers: top existing customers who will attend, prospects where a face-to-face conversation would move something email cannot, and the specifiers or engineering firms that shape short lists in your market. Begin personal outreach six to eight weeks before the show with a specific ask for a thirty-minute conversation at a set time, and aim to have roughly twenty meetings confirmed before you finalize the booth layout.
