Automate Data Feed Uploading into OSCommerce

I have a website, http://www.easymoneypawnshop.com. It is not ready to be published yet. I have set it up like I want it cosmetically, and have secured distributors who provide me with products to sell. The products are provided in the form of daily data feeds in csv or txt format, formatted for OSCommerce. I use Easy Populate oscommerce module to import the products. I need someone to help finish my site and make it functional. What I need: 1. Automate the process of updating the inventory. I need the data feeds from my distributors to be downloaded daily, and then manipulated to cull out certain items and items with less than X quantity, and take the price of the item and manipulate the price to include my markup, then upload this data to my oscommerce store and catagorize it properly into correct catagories. Basically, I need the data feeds from my distributors to be incorporated into the sites (with photos included) on an daily automatic schedule, and I need the site prepped to be ready for traffic. By being prepped for traffic, I mean looking it over to make sure the generic items that come with the template have been customized the way they need to be, or installing contributions you think could be helpful. I have already installed the shipping module for UPS ground only, which will be fine. And I will be setting up a payment module myself.
