Upgrading from Original Version of Omeka

I am pretty much begging for help here. The site I maintain has Omeka so far out of date that PHP upgrades are causing problems. Web hosts will not offer PHP 5.2 much longer. I attempted to update Omeka a few years ago, but there were so many issues that the back and forth with the forum took way too long so we went back to the original. Is there anyone who'd be willing to upgrade Omeka for me? You guys know what the errors mean and know what to modify in the database to make it work. The back and forth adds weeks to something that shouldn't take too long in the hands of people who really know what they are doing. Please, please, please.
