You can either hire someone to work right within your company within your office if you have space, or you can have them work from anywhere in the world. You can hire an assistant from overseas or you can hire a local person. It doesn't really matter what you do.
Virtual assistants you can sometimes find work from home moms who love that kind of work because it gives them a chance to work with and still be able to look after their children.
