I recently helped someone at the Angra archive get a certified copy. The staff pulled the book to make a copy of the page and took a 20 euro payment. They didn't have a notary on duty at the time so they took her USA mailing address since she was leaving that day. I can confirm that she did receive the certified copy at her home within a few weeks.
You will have to ask them if they can do this transaction by email and arrange electronic payment. Otherwise, do you know someone on São Miguel Island that might help?
I hope this helps.
