Quality English Transcription Services Needed

I am need someone to transcribe a number of live seminars and interviews. The seminars relate to business and self improvement. If things work out this will be an ongoing job as I have continued need for good quality transcription services over at least the next 6 months. Only people who are fluent with english need apply as I require very high quality transcriptions. In your reply: - Please state your experience and and also give me a ruff estimate of how long it takes you. Eg how fast can you turn around the project. - Please quote your price for transcribing per audio hour. ( per each hour of audio to be transcribe) Also if you have the ability to proofread and edit transcripts please inform me about that as well. Thanks.
