Are you effectively using the Internet to draw attention to homes in your portfolio or to find sellers? You really need to give details about what you are doing in order for anyone to give you advice.
On his profile it says Realtor, so I will go with that. Set up account at trulia.com and zillow.com to promote yourself. Don't use a template website they are not any good. Start a blog, seo your blog for your area. That should be enough to start. Don't spam trulia or zillow and you will build up a reputation, also only answer questions you know the answer to, don't just answer to answer. This may seem obvious but it is not for most people.
