SEO honest visitor traffic

Hello, I need an honest, experienced SEO expert to help increase traffic to several of my websites. I am looking for long-term results -- nothing to get me banned from major search engines. My first site already has top keyword ranking for several minor keywords, but I need help expanding that and get more inbound links and ultimately, traffic. I am hoping to find somebody to work with on multiple projects; this will be a long-term deal. I expect to pay between 100 and $300 per month for ongoing assistance. This is the assistance I require: 1) will review and improve my current website, 2) will handle the inbound and outbound linking strategy, 3) legally maximize the one-way inbound links, 4) report weekly/monthly on the success/improvement of my site within major search engines. Please list example keywords and sites that you have had results with.
