I’ll answer your question.
You find clients through a strategic mix of marketing communication potentially including but not limited to: formal networking events, informal networking, trade organizations, trade shows, public relations, a web presence, a social media presence, traditional advertising (potentially including but not limited to direct mail, broadcast, and out of home), online advertising, SEO, cold calling, third party websites, and referrals. Oh, and you have to do great work and have a great reputation.
All of that said, you’re asking the wrong question.
