Mobile Java Chat Application

Hey,
My company are looking to develop a mobile Java chat application compatible with the majority of mobile phones. Once installed, the application will allow up to 10 users to chat simultaneously in an on-line, real-time chat room environment.

User requirements

• Add, delete or edit entries on contacts list
• Initiate a private or open chat, invite other users to the chat. While chatting, message length is limited to 150 characters
• Receive an invitation to a chat and process it (accept, decline or postpone). Mobile phones will allow user to launch the application automatically, on receiving invitation
• Invite new participants to an existing chat
• Switch between active chats
• View other users' statuses (on-line, off-line)
• Read application help
• Change settings (enable or disable the sound signal that notifies user when an invitation arrives; change interval of server request by client application; save calls list; change server connection parameters).
• Bill customer per minute

If anyone feels they can take this on let me know and we can negotiate costs involved...
Thanks for you time.
