Site Map Script

We are looking for a free lancer to quote for the following script; I need to create site maps of some of the sites we design. I would need a script to crawl the ftp directory and then list the files in a tree structure. The admin section would then allow me to put actual page names instead of file names. In fact maybe I could include another meta that is reads realpage='home' etc... The script would be run on site completion and not every time a user looked at the page. The results would be outputed to a php / html page and be search engine crawable. eg home about us our ethos current clients web design logo design contact us Clickink on the site map would take the user straight to the relevant page. The script would beed integrating with another script to automatically set up the tables in a database. Thanks
