Buy An Existing Online Dictionary Code

I have a very simple dictionary dataset with 2 columns. The first column contains words in Language1 (L1) and the second column contains a translation of that word into Language2 (L2). I would like to purchase an already existing code that will allow me load in my data and operate a bidirectional (L1-to-L2 and L2-to-L1) online dictionary. Please include price and link to a demo site together with your proposals. Here is a short list of my requirements * I need to be able to preview the site * Strong SEO optimization is a must * Strongly prefer PHP/MySQL solution * Use of Ajax/Web 2.0 techniques is a great plus * I expect you to configure the site on my server (login info will be provided) * Ideally visitors would be able to comment on each word (captcha protected, no user registration required)
