osCommerce/OSCMax sites need some polishing and maintenance tasks

I have two sites, each running OSCommerce / OSCMax 2.51. I need to upgrade these sites to OSMax 2.53, create an automated back up routine, set up a product import from an Excel file and set up an EDI update via FTP. I am also using eMagicOne Store Manager for osCommerce which has an available plug in for Automatic Product Import, but this has to be configured/mapped. I did have a PHP programmer working on the sites who built it to the state it is in, but he was not familiar with the programs when he started so things may not be optimized correctly. We have gone from a sustainable/growing business to one grasping at straws over the past two years (since implementing OSCommerce from a basic HTML site built with tables), if something doesn't change soon it may all be for naught. Preview of sites: [login to view URL] and YourShipStore.com. Must have intimate knowledge of osCommerce/OSCMax, we have no budget for training a noob. There will be future opportunities with these sites, including shopping data feeds, mobile device settings, etc., as business returns to normal and we are able to expand.
