Build an aesthetically designed e-commerce website - $300 - 12 day delivery

We want to build an e-commerce website. We are looking to let people login through their facebook /gmail/yahoo accounts and make purchases. There should be verisign secured payment gateways and a neat interface for us to manage all pending orders in the back end. We are looking at 5 basic pages as listed below. The global view should also have icons for Facebook, twitter, FAQ, customer feedback and shopping cart. 1. Home page - slideshow of hyperlinked images 2. Store - online store 3. Ahalya Project - writeup and images 4. Causes - writeup and images 5. Track your Tree - Google map plugin Please look at the following websites for inspiration. 1. [login to view URL] 2. [login to view URL] 3. [login to view URL] 4. [login to view URL] 5. [login to view URL] What I like about the site are the clear white background, beautiful high definition pictures, modern fonts and look, and an altogether open and sincere feel to the site.
