You Own a Media Outlet that will:
ATTRACT OTHER ADVERTISERS, A SOURCE OF REVENUE, CREDIBILITY
Your Pinnacle Publications magazine is a real magazine, and has space for local advertising. You should have at least two pages of local ads, for reasons of income and credibility. The income could pay for your entire mailing, and the content of those ads - from selected high-quality businesses like yours - will add to your credibility.
In addition to approaching stores, services, professional practitioners, etc., you can contact ad agencies that represent national products in your market. And you can develop additional mailing lists through local advertisers. Pinnacle Publications will help you develop a "rate card" that sets prices, schedules and technical requirements.
