Bring min. 500 visitors/day to my website

Hi, I build a new wordpress promotion website for one product, but I have very small traffic (about 3 visitors a day or less), so I need to SEO may site for at least 500 visitors a day without any cheating. I install all plugins, FB like box, pictures and so on. I pay max. 100$ for this job, but first I need to see at least part results (100 visitors a day) to proof that you can realy do this job. For all informations please send PM!
