Growing your business. A lot of small business owners start their business and use whatever computer they had lying around at home to run the business. If they’re good at what they do, pretty soon they add staff and more computers. Over time the business becomes a collection of old computers that barely talk to one another and have duplicate files all over the place. It makes more sense to spend your time doing what you do to make money in your business. A good computer guy can save you time and money keeping your business equipment running.
