557656 Automated Order Import into OpenCart Shopping Cart via FTP

We have a completely set up functioning LIVE shopping cart (using OpenCart). What we are looking for is an automated cron to grab orders from our call center (via FTP) and have these orders imported into our Opencart Database such that: a) inventory control is maximized (item count goes down with each imported order(s).) b) the cron happens at a rate that does not tax the server but also keeps inventory numbers regulated c) after each cron an email is sent to the store owner to announce new orders imported OR each order is emailed just as if it were an email directly from a customer through the site as we currently receive them. d) the entire project acts as a module such that when it's time to upgrade the shopping cart, your work isn't overwritten. Useful Information: We're using Opencart 1.5.2.1 (most recent) Opencart is PHP/mySQL Data will be collected via FTP to our call centers server. They save the data in a format of our choice (XML,CSV,etc) and each file containing one or more orders is saved with a time and date stamp. Submit further questions and I'll try to get you answers asap.
