Site similar to electurelyte

Hello Freelancers, I'm looking for a professional freelancer who will design and create a website with similar functionality to eLectureLyte, but with it's own custom script. The site should be a fully functional, educationally-based, uniquely developed social network to be created with the intention of having users put themselves in an academic professor's shoes and record themselves teaching any subject that they wish. Having each lecture viewed and graded by their viewers. Visit the website and their intro video. I would like the whole package, script, graphics, logo, plugins, payment systems and your help with server configuration and testing. Logo name shall be provided, you must create logo. Everything should be configurable. It should be bug free tested via different browsers. I am looking for someone who has previous experience in this type of projects, someone who is reliable and can create a website that is customer and admin-friendly. Long-term cooperation is likely. If you already have a similar solution, I would be happy to have a look at it. You must be able to provide support within max 24hrs for the first few months and have the capability to provide future updates/upgrades (of course payable extra). If you are bidding, please make sure you send me your portfolio. Previous experience is a MUST. I expect a professional who knows what he is doing and how these services work, and who can offer advice and suggestions, not a minimalist who is looking for quick and easy money. I prepared a more detailed specification for those who need more information, please contact me if something is not clear or if you need more specifics. You must be able to present me draft/demo after 7 days of starting the project so I know we are heading in the right direction. Please do not start until I advise you to do so.
