דרושים פרילנסרים לבדיקת איכות של תרגום והוצאת translation certificate

We have an existing 3,000 words user manual for an app that was already translated from English to Russian and to Arabic.
For a customer request, we would need to verify the correctness of the translation and also get a "translation certificate".
We are seeking translators who can perform this job.
Thanks
