i have 26 amazon stores for which i need valid google xml sitemaps created. each site has over 5000 links in it. you will need to crawl them first and then create valid xml sitemap. for one site you will have to create multiple sitemaps because as per google guidelines each sitemap should contain no more than 500 links in it.
I need this done asap. No manual work required. You must have some software to do this else you can not do it.
