Write Admin Interface for File Hosting Service

I need an admin interface for a simple, browser-based file uploading service, written in PHP. The basic framework still exists, you need to extend it with the required functions below. The attached file contains the admin system as it is now, a very simple billing admin interface protected by a login-form. The following features need to be added: # Administrate customers: * List customers (with paging) * Search customer by name, username, user-id * Edit customer details (address) * Modify available space of customer (available_space row and additional_storage table) # Aministrate files: * List files (with paging) * Search posts by filename, show only from user-id X * Delete selected files * Change file details (size etc.) # Administrate posts: * List posts (with paging) * Search posts by text, title, show only from user-id X * Delete selected posts * Edit post details (title, text etc.) # Administrate bills: * Add paging support to the existing code Attached is also a schema of the database. Most of it should be self explaining, but feel free to ask about anything that is unclear. Your code should integrate nicely into the existing framework, style- as well as logic-wise. A couple more features/improvements are likely to follow in a separate private project after this one is completed, so I'd by happy if you'd be available for that too. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
