Chat with translator

Its basically ajaxIM and we have integrated google translate into it. It works fine for most of the languages except for some asian languages. A demo URL of the current system will be provided at a later stage. Requirements: 1. Make the site independent of the current site. i.e. it will have its own domain and hosting. 2. Registration Page. People come to the site and sign up. Admin should have an option to make the site paid or free. 3. Monthly payment can be different for different clients and free for some. 4. The add buddy should popup a form where users can invite their friends. A notification will be sent to their email address with some details of the site. 5. There should be an option to view the chat history. 5. Change the color scheme. We are thinking of making it look like skype. 6. All basic functionality should look and work like skype with translator. 7. There can be a voice and video chat. You can also suggest any additional features that will be beneficial. Please have a look at the requirements and let me know the price and time requirements. This is just one of many projects I have in mind.
