Customize WP Deals

I'm working on a daily deals website on Wordpress. I have the WP Deals plugin installed, and I love the look of everything, but I need some modifications to the WP Deals plugin functionality. You must be highly experienced with this plugin and Wordpress framework! I need the plugin to do the following on the front end: - Capture a shipping address at Checkout. - Fix an existing issue that says the product is out of stock. On the backend I need: - Separate each deal's order information and stats and have the ability to import it as a csv. file. If an item sells 100 pieces, I need to be able to export a file with all 100 names, email addresses, item details, and shipping information. Currently, this is only possible to do with all my orders from the month, but I need to be able to separate it by deal since I use multiple vendors throughout the month. - Enable stock availability. - Enable variations so that items can include different colors, sizes, etc.
