Need a Google Analytics Expert for One of my Single Page Website

I have a single page website. Please go to the website and take a look on it - [login to view URL] Home, About, Working, Contact, Imprint are different section of my website. Under About section there are several more sub sections. Like Profile , Experiences. And there are several widgets in each section. There are buttons and videos also. I know how to install simple Google Analytics in a web page. But that is not what I want. I want to track each and every single event of my website. I want that as a report in my GA report. Event base Analytics is possible (I know) . But i want that that will be done using key press event , link press event, browser scroller position(Remember that the site is responsive). How long a user is reading my profile. How long a user has watched a video in my website. I want every detail of each user . There may be 100 different things I can track. I want that an expert can help me and tell me what are the additional things I can track. S/He will also implement that GA Code in such a way that in near future If i want to add a new section in my website, I can do the changes easily. Please feel free to contact with me if any point is not clear to you.
