Looking for an Internet Marketing Expert

Hi, I have a website in a very niche area. Can you guide me on how do I increase relevant traffic and hence leads. I have tried almost everything SEO, SMO, E-Mail marketing but no benefits. Can you help generating more relevant traffic. (I am not asking for SEO and we are an established organization). I am looking for an Internet marketing expert who can guide me on how to generate more traffic. I need a complete proposal. Please start your bid with 'Lead & Traffic' so that I can understand that you have read whole project. I will tell you website through PM.
