Finding buyers is all about advertising and marketing. You develop a unique and creative ad campaign or marketing approach demonstrating why you or your products can be of value to potential customers and then advertise in media that your research shows your potential customers frequent. Check out advertising opportunities in magazines, newspapers, trade shows, trade association publications, online forums, SEO and PPC advertising. There is a whole world of choices out there you can use. Personal networking aimed at like minded individuals also works well. You can never beat that personal touch if you have something of value to offer.
Then, as they say on the shampoo bottle, lather, rinse, repeat until you succeed.
