25967 More website hits

I have a website with a Google PR = 5, and have done alot of SEO work on the website.([login to view URL]) I have about 5 keywords where my website is displayed on the 1st page of results. What I need now is to get MORE visitors, I have submitted my website to over 300 search engines already, have a few good links with other pr4+ websites. I have previously paid someone $150 to help with the "get more visitors" project, but he waisted my time and money, I had no results from his work. I want someone to do the work for me on a SMALL scale as a tester. I want to pay max $50 for now, and if i see that my hits/visitors are picking up, we can go ahead and do it on a full scale.
