Things are different here in PR, usually worse relative to the states.
Yes, its free in the states. No, its not free in PR. Yes, in the states, anyone who qualifies could be a notary. In PR, only lawyers can be notaries.  This helps keep prices higher than what they should be. It doesn't, or shouldn't take legal training to notarize a documents, as non-lawyers in the states can do the same thing, usually for free to $10 at most in the states.
Yes, I know that in PR, only lawyers can notarize documents. My questions remain, who are some in PR that have low rates to notarize? Their name, address, phone, cost? Thanks
