You could try to arrange for your salespeople to speak at seminars. Let their experience work for them. Only when you are out there will customers come to you. Always think like a customer. Don't focus on what you want to sell, but rather what the customer wants to buy.
Companies spend millions of dollars on brochures and advertising.
It only fuels a company ego. A good sales person will know this. Effective marketing is the only thing that will work in the long run. Every company wants to sell itself a different way. They want to show that they are unique.
