You will need a program to create the webpages, i.e., Publisher, Front Page,
Easy HTML and there's a whole bunch more.

Then upload the created files to your I.P.

A chat with your I.P. folks would  be a start. They may have suggestions on
which program and also advise you on how much I.P. server space they provide
to their customers.  You may need to subscribe to additional space.

I use Publisher 2000, my site isn't fancy.... kind of a Massey Ferguson but
it gets the wheat in.
