Consumer review website with rating,forums and newsletter

Hi, Under the brand name [login to view URL] I need a website built that will operate as a consumer review site for different products. Like [login to view URL] it must be able to carry advertising, run forums and have an easy to input and view rating system that then collates scores and runs top ten tables also needs to incorporate advertising and allow me to data capture for newsletter and marketing. I want social media linked in and the site to require little maintenance be easy to navigate and have an 'advice box with most recent asked questions from consumers and my answers on front page too.' I know that is a basic brief but the competitor site will aid you to see what I want and can take more questions and get into the detail. Let me know what adjustments to budget are needed if any.... Also looking to have same designer engaged to run maintenance monthly and updates at an hourly rate if they are interested. Cheers
