I am an experienced transcriber and I have done this type of work on other websites such as this. I've transcribed audio and video files. Raging from all kinds of accents and all types of subjects, including medical also.
Although my English is not my native tongue, I am an excellent speaker and I understand all sorts of accents of English language.
Hopefully we we'll have a good cooperation on this project making it into a long term collaboration.
If you need proof of my work, feel free to contact me.
Looking forward to hearing from you, Jasenka
