Despite the complexity of our latest subtitling project — transcribed, translated and subtitled in both Arabic and French — OSW successfully provided high-quality subtitled videos. They were strongly committed and went the extra mile.
I would highly recommend OSW for any type of translation. They are the only agency able to turn work round quickly enough to meet my deadlines for complex legal documents. They have never let me down.
OSW are professional, efficient and very user friendly! They recently met our requirements for a female Farsi speaker available on 24 hours notice to assist in three interviews. Where would we be without them!
We have worked with OSW for years. We are delighted with the quality of the translation service, the speed of response and the competitive price. Thoroughly professional at all times.
OSW's flexible approach meant we saved thousands of pounds on translation costs. Prices quoted by other organisations were much more expensive — and the quality wasn't comparable.
As a contracted supplier to the Healthcare Commission, OSW maintains a high level of discretion and professionalism, assisting us in improving communications with our service users.
