I will modify the wordpress core to display strings in 4 different languages. Let us discuss and move ahead. Are you there online to discuss and move ahead. Please reply

Hi, I'll be willing to do this at a fixed rate instead, at $150. I will create a custom language plugin with minimal code and db calls. I also like to know if the 4 langs will be static or dynamic

I would execute the task by adding a plugin that translate all your post title and content to the 4 different language and then when the page/post load, it also load the 4 different language. and then using javascript to display which language that the user preferred
