For EU I used
Digidentity | Digital Identity Made Easy and
https://www.namirial.com/en/- both automated signature verified that with an annual subscription between Eu 60 - Eu 80 (that was a while ago, numbers may have changed). They give you unlimited number of documents you sign by yourself once you are verified and they are deemed notarized meaning your signature is considered to be notarized but only for EU. I had used both a number of time mostly for signing a court documents to be used in Europe.
Once set up - and in both cases the respective onboarding processes leave much to be desired - it works very well, usually under 2 min per signature. Note that both provide a number of other services as well.
Digidentity is Dutch and Namirial is Italian based. Digidentity has customer service center in UK, Namirial in Italy so when calling Namirial one has to ask upfront for an English speaking agent unless one speaks Italian.
Hope this helps.
