You had a client that needs someone with medical transcription skills. If they charged such a fee, they would have to legally guarantee that they could find work for each worker. No one can viably do that. The registration fee for paperwork and such. My answer to this is that s a bogus line.
All businesses have administrative cots.
The charges they put on the employer should cover administrative costs. Also, this is a way of getting around the guarantee issue. They have you fill out about 10 pieces of paper and put it in a folder. They then place your name in a database. Went over my work experience line by line.
