Build a Website

I need a complete working site just like [login to view URL] in php with mysql. I want all the features which are used in the [login to view URL] should be there in the website including facebook, twitter login, (I need google login in place of VK) and the verified badge for the high-profile accounts. Not even a single feature of [login to view URL] should be missing. I also want a feature where a member can answer an anonymous question and only make it visible to the person who asked it. I want proper sql solution which can handle large no. of simultaneous user login and perfect mysql optimization and design and memcache or any performance solution support. Effective search algorithm. Overall the site should be exactly same as [login to view URL] and the work should look like completely professional.
