Another thing:
Things like Exchange Server, which is basically like having your own email service on your server which has many advantages, can sit there dormantly at first if you don't want to set it up. You can always use POP3 from each computer to your ISP and use Outlook or Outlook Express for email. Your IT person could then set up Exchange when you want to get more technical.
Adam and I both set up our network ourselves with a lot of help with some experts on the Internet and some books. We made many mistakes, some of which kept us up all night as we had to have everything working by 7 AM. But, it is a great learning experience. Whether you do it yourself, and I wouldn't recommend it or not, you may want to purchase a book on it. But, one resource I would highly recommend is the Train Signal courses. They are DVDs by Microsoft Specialists, and they are VERY good. The one on SBS 2003 is invaluable, and if I have to reinstall SBS 2003, I still use it for help. It isn't that costly, and it would be a good idea to sit through the DVD before any IT person installs anything.
