Answer:
The term that Russell should use here is recruiter.
Step-by-step explanation:
People often take a HR manager or professional as a Recruiter but that is not the case as recruiter is a person who is actually hired by the HR ( In this case he would be hired by owner himself ) to fill the vacancy available in the company. What Russell needs right now for his business is an recruiter who will help in taking care of recruitment process, testing the potential of the candidates and this recruiter will also look over the entire media communication about vacancy in the firm.
