Multi lang site with manual translation

Hello,

I have installed a wordpress with French lang. with lots of post and portfolio.

And now, I would like to translate all the website to English. I already prefer all the text in English (I prefer manual translation as it is more accurate)

Can I create same post twice and say 1st one is French and 2nd one is English

Please advise how to or any plugin that might help or can do that.

Thank’s
