ASP.NET MVC 4 - CMS / CMS Components (like Wordpress) -

I am developing a site in asp.net MVC 4 - the first code, EF5

Area sites require CMS functions - but I would like to drop MVC partially in the site - and MVC 4 (not MVC 2, or web form, say).

Ideally slotting into the existing MVC 4 app - instead of moving (but open to both)

Can I drop any MVC 4 'component' - or can I use full CMS?

Think ASP is equal to MVC 4 WordPress.

Requirements include:

  - Free / Low Price (& lt; $ 99) / Open Source - Good SEO Optimization - Easily add multiple images to one page, and Laying it - Adding new pages to the website - Editing Navigation - Friend's URL - Tagging - Social sharing button with appropriate page titles - Draft and prospective posts - RSS - Blog + comments - Polling - Contact form - Integration of Google Author All on the site Text Editable - Image Gallery, Click Image, Thumbnails - WYS IWYG Page Editing - and Template - User Friendly Admin Tool (Ideally No Technical / HTML / CSS Knowledge Required) - Store All This in a SQL Server 2012   
 Can there be a big advantage? (I am semi-committed to MVC at this point - although if there is a lot of harm then it can be persuaded to change).  
 Thank you
