553591 Imgur/Minus.com alike website

I would like to have an estimate in time and cost to develop photo sharing website like [login to view URL] and [login to view URL] All features as on the sites above + simple photo editing (could be made using CodeCanyon photo editors) resizing, tagging, red eye removal. Adding desciptions under pictures. [login to view URL], [login to view URL] and [login to view URL] api integration for easy sharing. Commenting using Facebook comments, Yahoo api. Sharing with all most popular websites using respective buttons. "Whats Hot?" widget showing most popular pictures based on last hour traffic to them. "Featured" widget showing most commented pictures since last day. Fully functional users galleries. Limiting some features to registered users only. Log in using Facebook, Twitter or Google/Register directly option. All images will be served by background server. Users can tag and categorize pictures. Users can report pictures. Few small addons could be requested but all fell in to the CodeCanyon alike scripts. Price should be for creating back-end (I will allow using ready to use scripts modified for our needs) and design. Successful company could be asked to further maintain website and work on updates as part of new long term contract.
