Sapphire/SilverStripe eCommerce Extention

I have two PHP projects that both need a CMS and eCommerce module. Both sites are 75% complete on the SilverStripe CMS running the Sapphire framework. Each site has been built in CSS/xHTML and the CMS and eCommerce modules have been implemented. What remains is to extend the Silver Stripe eCommerce module to do the following: * Up-selling and Cross-selling * Wishlist * Shipping will be tied into USPS * Merchant Gateway Integration * Tax Calculator * Reporting (this may already exist in the CMS) * Promo Discounts * Image Copyrights & Thumbnail Generation * Digital Downloads * Orders * Install Secure Socket Layer (we will purchase) DUE: end of August. Please send links to eCommerce PHP sites that you have created. If you have a resume, please send along as well. (We are hiring!) NOTE: once you extend the eCommerce for the first site you should be able to duplicate your efforts for the second site. They will function the same.
