CRM system (Customer Relations Management)

Hi there, I need a CRM system suitable for a web a design company. I plan to make it as automated as possible from my perspective. I need 4 user tiers. Admin (just me), Managers (to manage the designers), Designers, and Clients. Here are the features I need implemented for each tier. Client: * Calendar, for keeping track of due dates/milestones. * Ticketing, for messaging designers/managers/me. * Live chat, for setting appointments with designers, and talking to designers live. * Reporting, shows current progress, email reporting can be set up * History, shows order history, ticket history, etc. * Referrals, allows refer-a-friend, in exchange for a gift card or something. * Complain, allows complaints, goes direct to me. * Upload information, allows uploading of diagrams, images etc to show to designer. Designer: * Calendar, allows due dates to be set, and dates to be crossed off as holidays, in which they'll get no work. * Project tracking, shows current projects along with a brief description, can be expanded for full details including history of project. * Contact, allows messaging of client, manager, and me. * Live chat, allows appointments to be set with client or manager, and allows talking to them live. * Submit completed work, allows submission of completed work, which will then be double-confirmed by the manager, then me, and will then go onto the client for any modifications. If there are none, it will be then sent onto a coder. (who will have a pretty similar interface to the designers). * History, allows viewing of chat history and order history. Manager: * Calendar, will show overdue projects, and projects near completion date. * Customer Service, allows responding to customers pre-sales (although I may go with somewhere like liveperson for this). * Track projects, will track all projects under designers under them. * Chat history, will show chat history of designers. * Review work, allows reviewing of completed work before it gets forwarded to me. * Tickets, allows viewing, responding to, and opening tickets, with clients, designers, and me. * Live chat, allows appointments to be set, and live talking to designers, clients and me. * Unresponded tickets, view tickets of designers that haven't been responded to. * Staff list, view designers under them, number of sales, percentage overdue etc. Hand out bonuses to best performing. Admin: * Calendar, shows overdue projects, further individual details available if wanted. * Tickets, view tickets, open new ones, respond. * Live chat, set appointments, talk to people through the interface. * $ Reporting, shows ROI, gross revenue, profit. * History, shows chat history, ticket history, order history. * Referrals, view weekly number of referrals, revenue generated from them. * Project delivery confirmation, confirm projects are ok before sent to coder/client. * Survey results, shows results of customer satisfaction survey, which is handed out with the finished design. * Staff list, shows list of staff, managers shows designers under them, designers shows clients under them, revenue per staff member. * Reporting, shows full details of current progress on individual jobs.
