Your sitemap for the search engines does not have to be a fancy xml document. It can be as simple as a list of urls. A simple text file containing all the url’s within your website is all you need for a bare bones simple sitemap.

Something like.

http://www.example.com/contact.htm

http://www.example.com/about.htm

http://www.example.com/sales.htm

http://www.example.com/products.htm

will work just fine.
