I used the services of Schmidt & Schmidt OHG because I needed a new version of a personal document and an apostille stamp. I paid almost 600 EUR, which is rather pricy, but still much cheaper than the alternative (going to the country and arrange everything myself). The whole process from initial contact to receiving the final product took about 3 months, which I think is reasonable and there were no unnecessary delays. The communication with Valeria, my contact person was always good, clear and with fast responses. My involvement was going to the embassy and arrange a power of attorney, after this Schmidt took care of the rest. I recommend this service to anyone who wants to save themselves the costs of traveling and outsourcing most steps of this process. Many thanks to Valeria and the team for helping out, I appreciate it!
