Website language content verification & translation service

I’m looking for a language content verification & translation service for https://islamthereligion.com/.

This website was created by non native English speakers hence its English content would require language revision and proficiency improvement if needed.

The second service needed would be translation, It’s desired to translate this website into Spanish, French, Mandarin Chinese, German, Japanese, Russian & Portuguese.

It’s understandable that this job cannot be done by one individual so please reply with your area of interest.

No rush in delivery, time is not a constraint, the quality of the content matters the most.
