Russian-speaking customer service

I am looking for a Russian-speaking person (native) to support a client applying for a permanent residence card in Poland or for a Pole's Card. I have created a video course, audio course and written an e-book to prepare for the exam. I need a person to cooperate with me, who will help me with marketing, promoting this and will fill in applications for such cards at the office and will be in contact with people applying for these cards. I would preferably enter into cooperation with someone from Ukraine or Belarus because of their in-depth knowledge of the clientele. I speak Polish, so it would be good for the person to speak Polish at least B1 level.

Additional work. Max 10 hours per week.

The course will be premiered in two weeks, so I would like to cooperate before that date.

The proposed rate is 300 euros = per course sold and customer service on the application.
