Idea behind review world

I want a site that reviews everything from cars to blenders. Starting out by focusing on product reviews, while gradually incorporating service reviews. I want the site to contain professional/critics reviews along with consumer reviews. I want to prevent the user from continually having to look for new sources. There should be a central database that restricts bias and has all the needs for the potential consumer. Eventually I would like to link reviews to their products. Providing the user with the best possible deals without the hassle of searching for bargains.
