Create Corporate INTRANET

We need you to create a corporate Intranet(back office)(Portal, Document & Content, Management, Collaboration, Workflow) whatever you want to call it. We need a clone of [login to view URL] software. Need the same intranet but with our logo and name of the company. We don't need a clone of the [login to view URL] site. Just a product so we can use it for our company. Must be able to support up to 1,000 users and 300MB space(to share documents)You would also need to intergate it in our website. PM if you have any questions. Thanks
