34466 PHP Sitemap Script Changes

Need some changes made to a php script Currently the script creates a sitemap ( not google sitemap ), but only produces 1 sitemap no matter how many links there are... So on a big site the sitemap can take ages to load because it may have 1,000's of links on it... I need changes made so that the script creates multiple sitemaps, the number of links shown on each sitemap will be a random amount from between 2 numbers specified... i.e If i set to between 40 - 80 links per page, one map might have 43 links on it and another might have 66... Each sitemap will have navigation to all the other maps... So if 4 sitemaps are produced, there will be a link to sitemap 2, 3 & 4 on sitemap 1.. Need this done quickly... Lots of other work available for quick and reliable programmer... Payment by Scriptlance or Paypal. No Escrow... You can see from my feedback that im good for it..
