Did you find anyone willing to do this service - obviously electronic files and not shipping physical documents? I am also searching for the same, hence i ask if you found anyone?
Passports, utility bills and/or whatever is required to get offshore company regardless of type/location. Obviously notarized documents are needed to open offshore company (with or without business bank account) and NOT to apply for merchant account.
I don't understand your behavior OP! as far as I know @auric can get your docs notarized for €175 if you don't want to pay that much, go to your local notary service or find a local CPA / lawyer that can help you, done deal. It's you are running on a low budget which force you to search for something that don't exists and you waste a lot of time!
