I've spent substantial time today checking on OS X Server. It fills my projected needs exactly and provides for all foreseeable growth in a new company. The learning curve looks a little steep for someone who knows nothing about server administration, but I'm confident that there is good training available. Best of all, I can run it on my Mac Pro.
