I am sure you must have website and developed content with targeted keywords in it. I won't suggest you link building because today what is ethical that might not be ethical after 5 years. And I am sure you want business from your website for long terms. So I suggest create something useful stuffs within your website and share it with the community who need it very much. You will see your website automatically getting traffic organically. And due to that your website will gain popularity for your technology. Another thing you can do is, start your blog, showcase informative and quality content. Use long tail keywords in your content. I am sure you will be benefitted from these 2 activities.
