clickbank downloads site

I did this in the past but it didn't turn out quite right so I'm going to try again. I want to build a site similar to [login to view URL] (please don't bid on this unless you're familiar with that site) except that the site will be based on downloadable info products found mainly on [login to view URL] (again, please don't bid on this unless you are really familiar with clickbank). The site will daily update to include every product on clickbank with an automated rating system. People will be able to see a rating of products from clickbank with possible user reviews and then download it from my site (hoplink). I want to create an automated process that looks at product rankings, gravity and other clickbank statistics in a way I deam apropriate and have the system create an artificial "rating" (like 3 out of 5 stars) based on that. In addition I want people to be able to leave comments (reviews) of products that they have downloaded. I also want a function that gives them a rebate for the product that they downloaded in exchange for writing a review. Also, each download page should capture description from sales page of each product and include it in description section. Thanks much for your time and bids
