Integrate a Social Community for a custom website

Hello, We run a custom made website that was built by another company and need a final project done in order to make the website fully functional. PLEASE VISIT [login to view URL] TO FULLY UNDERSTAND THE WEBSITE IS ABOUT!!!! Our website allows users to upload a video of themselves singing and compete with other users online by allowing visitors of the site to vote on the better singer. The website runs on ExpressionEngine v2.3 and has alot of custom coding to make the voting system and user login work. Users log in with Facebook Connect and can then "Create a battle" using their own video or with a youtube link they provide. "Creating a Battle" means that they create a video of themselves singing, go to our "Battle" section and then click on "Create a battle" to start the process. At this point, the user then gives the "Battle" a title, provides the link for the instrumental they used for others to use as well and either uploads their own video or provides a YouTube link for them to embed. Other users can "Join The Battle" by following the instructions after clicking the "Join The Battle" button. Now that you know the most important aspect of what our site is about (A Hip Hop Battle Website), we would like to create a community in which users with profiles can have somewhat of a place on our site to provide some background information, embed a YouTube video of their choice, a music player for them to upload their music audio tracks for people to listen to, a friend request system, a guestbook/comment system, private messaging etc. We also need on the home page to add a "chat box" that carries over into our battle and blog section and a way to highlight any members profile that we choose. We also want to create a link on our page to point to a "Community" area where we would like the following to be implemented: - Most Active Member (A snapshot of the members profile based on how many battles they create) - Most battles won (Snapshot of member who has won the most battles so far) - Newest members who made a profile - Activity (Info when a member creates or joins a battle) - Chat box that carries over into other parts of the site We also need a system when a member can challenge any other member to a battle (Maybe a button that someone clicks and the member receives a private message with the link of the member who wants to battle him) Its very important that you understand how the website works. The only way a person can create a battle is by signing in using facebook connect. Any time someone who visits the website wants to vote they have to sign in first to vote for the video. Please visit the site and become familiar with everything. We also need a way to edit the title of a battle once they are created in the expression engine module. Our previous model we had in place was using ostube script but needed a custom website to get the functionality we needed. The website is already created, we just need to add that functionality to the site in order to make it more user friendly. ***Important*** User must recreate the site on another server using our files to work on the everything and we need to be able to test before payout. The company that we have used is no longer in service, we only have the cpanel login information and our expression engine login. PLEASE INCLUDE PAST PROJECTS YOU HAVE WORKED ON to see if you are capable of doing what we request. You must be able to communicate exactly what you will be doing. We need to work closely to reach a final product. ****IF YOU DO AN EXCELLENT JOB WE WILL HIRE YOU AGAIN TO IMPLEMENT AN ONLINE STORE TO OUR WEBSITE AS A BONUS*** Please ask us any questions before bidding! View the attached photo to see a rough draft of how the profile can look like but does not have to follow that.
