If you are serious about the quality of the translated pages and posts in your WordPress estore then I would suggest this premium plugin - https://wpml.org/purchase/
The prices are $29, $79 and $195 - depend on their features.
The default install comes with over 40 languages. You can also add your own language variants (like Canadian French or Mexican Spanish) using WPML’s languages editor.
You can arrange different language contents in the same domain (in language directories), in sub-domains or in completely different domains.
If you need help with translation, WPML connects you with a huge pool of qualified professionals.
Choose your translators and send content for translation directly from WPML’s Translation Dashboard. When translations complete, they appear back in your site, ready for publishing.
