<Recipient Address Goes Here>
You know the costs of printing materials, running ads in the newspapers, and sending out direct mail. It's expensive. But I've got a potential solution. I have been very impressed with <other company name> over the years, with your professionalism and your vision. So I would like to suggest that we make the most of our revenue and pool our advertising dollars.
By doing things like <proposed combined projects>, we could increase our bargaining power and cut better deals with local vendors and media outlets. This seems like a natural way to get more for our advertising budgets, and I can think of no other company with whom I would rather work. If you're interested in discussing the possibilities, give me a call at <phone number>. I look forward to speaking with you.
