OpenCart mod update

Hopefully a quick and easy job for someone proficient in PHP and knowledge of Open Cart - Automatic generated password at checkout and mails the password [login to view URL] I purchased and downloaded the above mod yesterday but it does not work on Version 1.5.6.4 which is the latest version. Therefore I need someone to update it for me so it does work on the latest version of Open Cart.. I have attached the file which I downloaded so you can have a look at it before bidding. This should take a decent programmer no more than 30-60 minutes so don't bid silly price as you will just be ignored/deleted. I also want this work completing today. Note: No FTP access will be given to our server. All coding and testing must be on your own machines and completed work delivered as installable VQMod file (within a zip). No payment released until I have tested it and am satisfied.
