Wordpress WP Deals Plugin Custom Development

I want some custom development done on a WP Plugin, WP Deals ([login to view URL]). The Plugin works 90% of the way I want it to, however I want the following features: 1) Allow product deals. Currently there is only the option for vouchers or downloadable items - I want to setup deals for physical items 2) Integrate Payment Express/ DPS as a payment gateway 3) Create a download order functionality which would download a CSV list of orders with the following information to send off to the supplier: - Order ID - Order Status - Order Items - User Shipping Address - User Billing Address Please provide me with a quote, then break it down into each item listed above.
