Hello,
I see that you are looking for Bulgarian transcribers so I decided to offer you my services.
My name is Dimitar Zlatinov and I have been working as an English>Bulgarian translator since 2004 so I am aware of this type of jobs. I am a native speaker. I graduated English Studies in 2007 and since then I work in an automotive company in Bulgaria, Plovdiv, translating service booklets, guides, training courses, etc.
I also work as a translator translating movie subtitles for an American company, Deluxe Digital Studios/Sfera Studios, for Blu-Ray/DVD, cinema releases, digital download, and TV broadcasts on various topics.
You can check my profile in case you are interested. I will be glad if we have the chance to work together.
Looking forward to your answer,
Dimitar Zlatinov
