Build for me a Document Management System using Django Framework

I am looking for someone who can develop for me a Document Management System (DMS) using the Django Framework. The system should be able to allow scanning of documents and be uploaded to the cloud. The documents are then labeled and indexed in the cloud to allow easy retrieval and searching by users. Users of the DMS should have different access rights including those who can manipulate and those who can just download the document. Ideal candidate should have experience handling Django platform, Python, PostgreSQL, HTML5, CSS3, jQuery and other relevant technologies.
