Why Do I Need to Pay A Professional, When I Could Just Buy Microsoft FrontPage and Do It Myself?

Certainly, that is an option, but you need to be careful not to underestimate the power of the first impression. If that critically important first impression is a bad first impression, the potential customer spends 2-5 seconds and moves on...never to visit you again. If your site creates a good first impression, the potential customer wants to learn more and visit other pages. Neither should you forget the vastness of the potential audience; the Internet is accessible by nearly the entire planet.

Think of it this way: Say you are going to place a full-page ad in the USA Today. This is going to cost you 10's of thousands (or more) per day. Would you create that ad yourself? Unless you are in the graphic design/marketing industry and have very good skills in this area, it would be crazy not to pay a professional to have it done right. Your website will be up forever, not just one day and, over time, it will reach many, many more people than the USA Today ad. Your company's website is a very important marketing tool and it needs to be treated as such.
