Thoughts on Outsourcing or hiring VAs...

I would like to know people's point of view regarding outsourcing or hiring VAs than the traditional way of renting a physical office and hiring personnel to do office work.

For me, I believe that outsourcing is the way to go since it is the most inexpensive way to operate a business. You don't have to rent a physical office and hire a lot of personnel to do specific work for you. When hiring VAs, they can do multitasking.

Please share your thoughts on this especially the pros and cons.
