Build a web based full chat room system with full admin and webcam features and other functionalities

We need a full chat system that can support thousands of users concurrently with full webcam features. The chat must have a modern and nice front end design. We will give some examples of how we want it to look. Here is an outline of some of our functionality requirements. Full Chat System: 1) Webcams/audio functions privately and publicly. - Those showing their webcams will have an icon beside their name. Others can view them and do not need to turn on their own webcams to view. - Private one on one webcam also allowed. (again other person does not need to turn on cam) 2) Flood control system - repeated messages are automatically muted. - those who violate this multiple times are booted and not able to return for set period. 3) Change Avatar - system will be able to upload picture and resize to system avatar specifications 4) Guest/Registered Login System - can choose to chat as guest or can become a registered user. Integtraton with existing MariaDB database systems also possible. Logging in can select gender. Guest user data are not kept. [login to view URL] Refer to [login to view URL] 5) Select font size, color, face - ability to select this by user 6) Smileys - Ability for Admin to add custom smileys to the room. - Room will also have standard smileys 7) Advertising bot - Can set the url and text used to advertise in the admin. Text will scroll every "x" seconds as specified in Admin panel. 8) Full Admin/Moderator system - create rooms - rename rooms - assign new moderators - can ban users - view IP addresses - kick users - mute users - add/remove by IP address 9) Ignore/Block other users - Users can block or ignore other users by selecting their name 10) Private Chat - can message users privately and open a new tab with the private chat. 11) Filter words - can block bad words set in the admin panel 12) Image transfer - ability to share image with others. Need thumbnail preview and upon click show full image - Images can automatically be pruned entirely from Admin panel - images sent can be seen under a tab. Please refer to [login to view URL] Refer to: [login to view URL] Refer to [login to view URL] 13) Userlist sorting by roles Such as: Admin>Moderators>VIP>User Colors by roles 14) Public chat history. - Can delete them or save them 15) OAuth Social network login/Forum: - Login via major social networking such as Facebook, Gmail, Twitter. - Saved by cookies/cache to database and can remember user so they dont need to enter information again. - Login from our forums 16) Notifications - When receiving a private message or someone @ someone they will receive a pop up message (if they turn on notifications) 17) Messages can be liked, thumbs up, etc and replied to such as [login to view URL] has. - refer to [login to view URL] 18) Idle timeout - when user has not typed or did any action for X amount of time (set in admin panel) he will be dropped from the chat. This is to save server resources. 19) Profile system - Users can set their gender, age, contact info, etc. 20) Use sweet alert system - For confirmation of things in Admin panel and on regular chat. - refer to [login to view URL] PRIVATE CHAT SYSTEM: 21) Having the typing message "..." showing when someone is typing beside their name 22) Age Restriction system for registered users: - if they register their username and age, they will be allowed in certain rooms based on age. - use sweetalert to block them from the room if they dont meet the age requirement. Emphasis should be placed on 1) Security 2) Stability 3) Modern Design
