I need a sitemap that I can submit to Google Webmaster tools. I am talking about a website, which is showing around 39,600,000 results for "site:domain-name.com" I know that a sitemap can contain multiple sitemaps (lets say 20 or 30 etc). This is probably what I would need to do. Do you have an idea where would I create something like that, and preferably for free? Thank you.

If you're on Wordpress, download and install the plug-in "XML sitemaps". Then download yoursite.com/sitemap.xml and call it a day.
