Not in order, but one thing I appreciate is a back-up system like Carbonite. It works like a charm and the cost is reasonable for a year. Also, get in the habit of using back-up recovery disk every day. In this way, if the unthinkable happens (insert prayer here!!!), you can pick up where you left off.
Debbie's idea is very good, you need a back-up spot.
I have done resume's and at this time I am not certified, but I am working on it. No one has asked me for certification as of yet.
And lastly, I love the tagline: "E-Navigation: Where Can We Take Your Business Today?"
