Digg/Reddit clone. Ruby on Rails, AJAX, XHTML, PostgreSQL, memcached

I am soliciting bids on a new web development project. The website to be developed is similar to Digg and Reddit. It will do the following: * allow user login/register, with email and turing test verification * allow users to submit new items * allow users to vote on items * track item popularity and derivatives over time * popularity algorithm implemented with "strategy" design pattern to be replaceable later * allow items to be sorted/filtered by popularity and derivatives * allow items to be tagged into a category directed graph (similar to category tree, but with multiple inheritance) * allow items to be filtered by category browsing * allow items to be searched/filtered by title and description * allow items to be commented upon * allow users to vote on comments * store user submission and vote history * have a moderation interface to allow moderator to ** review submitted items ** edit items ** add items ** delete items * HTTP ReST API for adding new items and moderating * RSS interface to search and filter functionality * "item" class must be generic and subclassable for different types of objects. concrete examples may be news articles/hyperlinks, images, videos, audio files, etc. * small-footprint mobile interface for all pages in valid XHTML-MP * mobile devices detected by User-Agent string * FAQ section, driven by database * Contact page * About this site page * Front page should display results of a "canned query" as outlined above. canned query must be tunable. I can provide an initial navigation sitemap I have created for this site. I look forward to a quote from your company. Please do not hesitate to contact me if this RFP is unclear. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows: a) Application ource code delivered in .[login to view URL] format b) Application and dependency libraries delivered in RPM format, compiled for CentOS Linux 4.0, either noarch, 32-bit, or 64-bit. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
