Spanish Notary for Academic Transcripts

I need a licensed notary based in Spain to officially notarize my university transcripts. The originals are already in Spanish, so no translation is required; what I am missing is the formal notarial stamp that Spanish institutions will recognise. Here is how I picture the workflow: 1. I email you high-resolution scans so you can verify authenticity and prepare the notarial wording. 2. Once you confirm everything is in order, I courier the physical transcripts to your office. 3. You notarise each page and return the stamped set to me by tracked mail. If obtaining an apostille from the Colegio de Notarios or the Ministry of Justice is something you can also arrange, please let me know To be accepted, the documents must carry your visible notarial seal, date, registration number, and signature, and they must be issued on official notarial stationery so they are immediately valid at Spanish universities and government offices. Kindly tell me your turnaround time, the exact address where I should ship the papers, and any identification you will need from me. Looking forward to working with you.
