Hiring virtual employees is no more expensive than hiring in-office staff. Overall, you have the same recruiting and staffing costs that come with hiring any employee.
In fact, it can actually be cheaper to hire virtual employees. First, you won’t have to fly candidates in for an interview, because you can conduct them remotely. Second, if you live in an area with a high cost of living where people command high salaries to compensate, you can hire individuals from outside that area for a cheaper salary.
