Account Management System

We are currently looking for a freelancer to integrate multiple programs into one easy to use module for our clients. The program is basically a client area. Within the client area, clients will be able to view any outstanding invoices they may have which are created from the admin area. They will be able to change contact information, billing information, and passwords from the area as well. This program must also act as a signup area as well, taking orders, processing them, and automatically setting up the accounts in DirectAdmin upon successful payment. The payment module we use is [login to view URL] so it must integrate with authorize.net. Billing informtion must be secure within the database for easy use for automatic billing. The admin area must include the ability to add new packages that can be ordered through the shopping cart panel, view current clients, view outstanding invoices, suspended accounts, view account information if a client is going over their usage. Invoices must be generated automatically along with the suspension of services for lack of payment. Invoices also should be generated automatically if a clients usage is over his allocated amount for any given month. The support system must integrate with DirectAdmin's current ticket system and should be able to parse incoming emails to set them up as tickets. In short the program must contain the following: -An automated billing system integrated with [login to view URL] -Must integrate into DirectAdmin's current ticket system -An automated shopping cart for new and existing clients to add services -An admin area to view current stats of all clients including paid invoices, outstanding invoices, current server stats, etc -Everything is automated -Client area must include area for tickets (integrated to DirectAdmin), view current invoices, pay bills in advance, update all information, add new services or addon packages.
