Well, there are many avenues you can take. If you are going to go with someone to professionally design a web site for you, ask for references and to see web sites they have created (their portfolio).
My other idea is create a blog on a free blog site like wordpress.com. You can add pages to your blog....bam...instant web site (as instant as you can get without many other design programs, etc, anyway)! They have a variety of templates to choose from. I know there will be other great ideas from the rest of the VAs, so be sure to keep checking the thread. You can find loads of information and help about setting up a blog in the
blog and blogging section on this forum.
Hope that helps a little.
