Hi Greetings,
With me having an experience of over 15 years in the field of transcription in all general, medical and legal transcription of late, I can propose myself as very suitable candidate for the project.
Also, as for subtitling, I have been doing that for the last two years for all kinds of videos ranging from small videos to Discovery TV shows. I apologize but I can't tell you the tool we use, but yes I can fulfill all kinds of your requirements for the same.
I hope to hear back from you soon to discuss the project further.
Thanks and regards,
