Looking for official translation: basic divorce decree, from Dutch to English

Good afternoon, I am looking to have my one-page basic divorce decree from the Hague officially translated from Dutch to English, for the purpose of using it to legally change my last name back to my maiden name with the American Consulate on my US Passport.
They will only accept the divorce decree if it is officially translated, by someone with certification to translate legal documents.

Would you please let me know the approximate cost for this service as well as the anticipated time frame to complete it?

Thanks very much in advance for your help.

Kind regards,
Amy
