Virtual Assistants, or VAs, have been a growing part of the "gig economy" for several years. While the folks on eLance and Fiverr generally occupy the artistic or creative roles, VAs usually perform office-related tasks. Need someone to book your travel reservations, process forms and paperwork that you might think of as routine, make calls or do research for you? Consider a virtual assistant and free up your time for your core business work.
