392353 OpenVPN Admin Panel

Need to have OpenVPN installed so that I can have users browse the web securely also need an Admin Panel installed on the same server where Users can be added, deleted, expiration date set, and check amount of bandwidth used by user. If you already have an Admin Panel please provide sample screen-shots or live link for demo. And need to have all the steps taking writing down in detail so that if needed I can do the reinstall my self, if any questions please let me know.
