Hello from the Philippines!.. I'm an American who has lived and worked in the Philippines for the last 10 years, and have accomplished much in the transcription field. (see my profile please!)
My rate for your prospective 10 transcriptions would be based on $22 per audio hour. My extensive experience with editing combined with having a international ear for syntax gives me an advantage in having transcriptions flow. Also practicing English as my first language for near 60 years now sort of helps!
While it takes 3+ hours per audio hour, my total turn around time would be 24 hours, when needed, assuming your audio quality is sufficient. Will edit out unnecessary "circle speak" and mutterings automatically for you.
Most of all, to have you know that everything I do is based on integrity, therefore it follows that you can relax knowing that for what we agree to, it will be done so, with the highest level of expertise.
Good luck with your project,
and thanks for the consideration.
