Hello,
As native spanish speaker I can complete your request with no issues. Although you say that you do not need help with translation, I can even help you out with that if you somehow require it later. I will give you an editable document with the full transcript with in a format at your request. After finishing, I will be available if needed for making corrections or improvements to the transcript, so you have the best quality work, if possible.
Do not hesitate in contacting me if you have any inquiries.
