there are two different sitemap generators that we offer:
1. *Free* Online Generator that works on our site: http://www.xml-sitemaps.com/
where you enter website URL and it creates the sitemap, then you should upload resulting sitemap files to your site. This generator is *limited* to 500 pages since it's running from our server.
2. Unlimited Sitemap Generator is a PHP script that you install on *your* server and it creates full sitemap for your site. This software costs $19.99, but is not limited with number of pages and has more configuration options.
