Adult Website(AVS) - Page language translation

I want someone to add language translation functionality to my adult video website. Currently my script only translates the website text itself. I want my website to translate everything including video title, description and users screenames. Basically I want the whole website to translate not just the website text itself. I also would like a dropdown menu on the main index page with the country and flag. that was the user can change language by flag or by country. Another mod I would like to have done in the project is I would like the website to get a location of the user by their ip and display the website in the correct language for the country. I want to be able to turn that feature on and off in my admin settings.
