We have a site with a large number of pages (50,000+) and we are looking for help with creating a Google Site Map. We have tried to run the SOFTplus GSite Crawler but have encountered a few problems. I'm willing to pay someone to help us out with this. It doesn't matter what software is used, just that we end up with a valid site map that we can submit to Google. If you're interested in helping us out with this, please reply to this post or PM me. Also, if the more appropriate category for this is "Buy, Sell or Trade" please feel free to move it. I figured that I would probably get a better response here. Thanks!
Have you tried an online one? http://www.auditmypc.com/free-sitemap-generator.asp claims to support 50,000 pages.
We tried that one a couple of times but it keeps crapping out on us. We'll let it run and it will go for a while and when it comes back all of the threads will show as terminated.
