PHP Google Docs Class

Hello, I'm looking for a coder to create a Class in PHP for CodeIgniter or similar to work with Google Docs. The features I need to interact with Google Docs API are: - Open Office files in Google Docs (for example if we upload a .docx to a directory in a server when clicked it will open that file in Google Docs to edition). When saved, save the file in the same directory in the server as well. - Embed editable Google Docs (if possible). - Obtain info from file and folders in Google Docs. - Obtain a list of the files and fi - Access to a specific Google Account or more than one account. - Create, edit, move and remove Files. - Create, edit, move and remove Folders. - Upload and Download Files. (I know that some are possible, others I'm not that sure, so please advise me in which are possible and what we can get more from their API). The Class needs to work in a Linux, Apache, MySQL and PHP systems and all the browsers possible. This class will interact with another part of the CodeIgniter app.
