439941 LOOKING FOR HELP ON JOOMLA SITE

We are using Joomla 1.5.20 and looking for help in optimizing SITE, scripts and current template. The tasks needed are: 1.- Checking and optimizing all core scripts (to keep hosting server resource from over-limits). 2.- Modifying current template, or install new one, to work perfectly with Joomla 1.5.20. A similiar looks and functions template would be OK. 3.- Enabling Joomla "SEO" function to have short links. A similiar plug-in may be OK. 4.- Checking and cleaning up all orphaned folders, files created by modules, plug-ins.... which are NOT in use. 5.- Any needed adjustments to make sure that the site will run properly with current server of Hostgator and to avoid errors. ------------ I will provide more information upon requests. Please note that I need at least a week after the project done, to be sure that the site has been properly fixed and optimizing. Thanks BEN
