Creating a web page / blog as platform to post stories

For a university project we are building a website where Londoners can post small stories, anecdotes or snapshots of London life, just to share something nice. We want people to share it with the world, so when people see a picture of someone doing a good deed they can feel that London is a community. Real people that are kind and caring to others are not credited enough! This idea will promote and link good deeds in the big city! Especially in light of the riots in London we want people to remember that there is a community of caring people who want to be there for each other. The website needs to have similar functions as [login to view URL] and www.truelad.com. Users can post small stories from everyday life and other users can rate the stories by giving them “thumbs up” or “thumb down”. An important feature of the site is the possibility to “like” it to Facebook, re-tweet the posts and google+ it. Also, users should be able to comment on the posts just like they can on the other mentioned websites. I don’t know how this works: do we need to let people create a user on our site or can they simply connect with fconnect (Facebook connect)? The stories that get the most likes should be ranked in a table, resetting itself each week to zero. The idea is that the ranking system works as a “karma account”, where a good ranking equals good karma (something you deserve to get when you do something nice for somebody else!). Important: We want the site to be as clean and simple as possible, only with these basic functions on it. We need it as soon as possible. This being a not-for-profit school project, we have limited funds but we understand that building a site like this costs money. We would like the following basis functions: Function to create posts and upload pictures An admin function that would allow one person to approve posts of pictures and comments The index/main page should be where the blog posts are shown. In addition, we need a privacy disclaimer page, terms and conditions, about, contact etc Ability to like, thumbs up, thumbs down, and retweet, facebook connect, re-comment, google + In order to win the job, we would need a sample portfolio of previous work completed. Are you capable of completing the project in a 3-4 week time period? Are you familiar with all of the applications we need for this website?
