No need to make 2 separate websites . Just use qTranslate.
It is hands down the best solution for multilingual wordpress installation, and I myself have used it with over 100 multilingual sites
The management and maintenance would be much easier , you will have a control over all aspects of the multilingual behavior and you could SHARE resources ( like scripts, images , themes etc ) .
With this plugin you can choose if you want to have a URL like :
http://www.mysite.com/fr
andhttp://www.mysite.com/en
http://fr.mysite.com
andhttp://en.mysite.com
http://www.mysite.com/?lang=fr
andhttp://www.mysite.com/?lang=en
All your users will see is a small flags based or menu based language switcher .
The Admin screens easily share languages , switching, and content handling . Even switching the admin area language itself is a breeze .
You even have control over local SEO.
Every aspect from title to media to custom fields is also supported . Basically you have duplicate fields for title content etc . The best way to understand is just install one time and start to use .
you will get the idea in a second .
It has a very extensive hooks base and custom functions that allow you to easily do virtually everything !
Example of a working ( old ) wp install with qTranslate supporting 5 languages can be found here
P.s.
I am in no way affiliated with the author of this totally free plugin - But I do admire the work he has made and the techniques used in his code . If you end up using it - a small token of appreciation for the author would surely be appreciated by him .
Edit I after comment.
Grammar or the correctness of the translation is irrelevant .
qtranslate is not an automated translation service / plugin
It does not really translate your site , but gives you the tools to do so in terms of UI, accessibility, functions and hooks.
The actual content is translated by YOU. No automatic content generation ( unless you specifically want one )
It actually does create 2 different websites ( in a sense ) but using the same install, core files, resources etc ..
Until you will not try and use it , you will not fully understand how it works.
