I am taking a web and e-commerce class. I am a baby in the woods. As
part of the class
I am creating a simple web site for my husbands custom cabinetry
business.

I can see already that the world is a big place. I am asking for any
simple and sensible
advice any of you more seasoned internet travelers may have. What
should I beware of
and what is a great opportunity? Any thoughts or suggestions?

Thanks for any help you may have for me.
