Web2.0 website with Questions & Answers formula

IF YOUR OFFER IS TO BE CONSIDERED YOU HAVE TO PROVIDE PORTFOLIO WITH STRONG EXAMPLES OF PHP, MYSQL, AJAX, FACEBOOK CONNECT PROJECTS. ALL OTHER BIDS WILL NOT BE TAKEN INTO ACCOUNT. The project is a website with the Questions & Answers formula, where user can ask a question to search through the database for same / similar questions. If the search is not successful user can decide to add the question, which will then be available for other users to answer. Other users can answer the question and each answer can be voted on by users (Do you agree YES or NO), so that each question has it's page with all answers given sorted by best answers. My project will differ to all known Q&A websites, because questions will not freely entered by users, they will only be able to pick an answer from predefined answers, which exist in the database (more details will be provided for the bid winner). Other key deliverables: - admin panel to manage questions, answers, categorize them, if 2 are similar replacing two questions with one - admin will also be able to load pictures as predefined answers, where pictures will be automatically resized to 2 fixed formats I will provide the layout and graphics in PSD files, so design is not part of this project. KEY SKILLS REQUIRED: - PHP5, MySQL, - (X)HTML, CSS according to standards (no tables to build the layout) - strong AJAX experience - Facebook Connect and Facebook Like experience
