Zen Cart, PHP Script, SQL work Required

Hi, We have a script on our website which allows us to upload our datafeed from the supplier to our website, and then gets the images and descriptions from icecat. We had to do a lot of work to the site and now this is not working. We have all the php files uploaded to the server, but we do not have the sql database files. We do have an old plesk back up, so we require somebody to extract the database files from the plesk backup, or create new tables for our script to work. The php files have been encrypted with zend, so you will need to know how to deal with this, we also have a button that allows us to export our own feed, we have the file for this, but it needs adding to the site, so we can use this function. This project needs completeing really fast, so please ensure to inform me when you can start and roughly how long you think it would take. Please remember we have the php files in place, we need the sql database files creating, or being used from the plesk backup zip file. Once completed we would need a copy of the sql files for backup purposes. Please only bid if you can complete this project in a fast time
