I wanted to cut straight to the point that Rosetta is my recommended translation agency. This company provides a reasonable price of document translations to costumers all over the world! In fact they got 5 global offices located in London, Shanghai, Paris, New York and Luxembourg. But if you are not in these areas, you can easily reach them through the internet! Rosetta Translation Agency can translate many languages including French Translations and they are renowned for their quick, high quality and reasonable pricing.
To be honest, I have not been a costumer of Rosetta Translation Agency but my husband works from one of UK’s charity organization and they always use Rosetta for document translations whenever they needed one and they have not got any problems with them. He added that based on experience, all instructions where carefully followed and you can have your documents certified, legalized or notarized if required!
Oh, before I forgot, the company specialise in business and commercial document translations, and they do offer very competitive rates compare to other translation services so get in touch with them! Based on what I know, you can reach them through email or by phone if you got any inquiries. You can find their contact information at their website or simple click the link provided above. All the best!
