Urgent fix needed for Joomla/Docman/XMP integration

I have a very important image based site with 140K images, I had an XMP soution integrated with Autopopulate for Docman which worked perfectly, however, due to work undertaken after the modification was done the XMP data extraction and import to the database appears to have failed or at best is intermittent. This is a critical requirement for the site so I need it fixed. In addition I need a script created to scan every existing file and add the XMP information if it is missing. So, fix the XMP system and check all existing files for XMP data and add/update the database. Skiner, if you read this you have the job, just need you to contact me, you have my contact details! More information needed? Just ask. Need this done quickly though, so only bid if you are familiar with Adobe and XMP in jpg images and extraction of the information into a database.
