Everything went with a bang!
I just clicked on the first company that appeared on the Internet, "My Planet" opened. Very polite staff and explain clearly. Of course, next time, I will only contact them. Special thanks to Nastya and Yulia. Helped to choose a tour in Bulgaria in the ski resort of Bansko. The hotel was Mountain Romance (Mountain Romance) 3 *, 10-15 minutes walk to the ski lift, a quiet place by the way.
