I did a power of attorney, I came to 12 there was no queue, they said to pick up the finished document after 14, waiting on site for less than an hour, the cost of the power of attorney is less than 100k for three years (representative). Everything is cultured and polite.
In addition to the words of gratitude, I can mention 3 main, significant and important points:
1) Highly qualified,
2) Impeccable professionalism,
3) Sensitivity and attention to those who have returned.
In one phrase, you can say: CADRES DECIDE EVERYTHING.
