PHP script for Server

I want a server script similar in function and layour to Google docs Basically ability to add projects as if it were a spreadsheet and manage info Includes Add Project and I can insert and edit such as -domain name -keyphrases with corresponsding URL's -plus several other pieces of info Then when you open campaign/project, there are tabbed pages which when selected open up into columns where we can enter info, just like entering onto a spreadsheet. Needs to be able to copy paste info in from an xl sheet The server script would run under a domain and access to campaigns will be independent through login and passwords with one overall admin login which access to all projects Also preferable is you have knowledge of Google/search engines API Must speak excellent english Available Skype/msn Basically this program will monitor projects and let third parties upload info as though they were on google docs but now on my server Project would allow prinitng or exporting of this info on these campaigns If you have done some previous project managemnt server scripts that would be an advantage Thanks
