I have a pretty simple site to do. I already have a wordpress theme that I designed the mockups to follow so you don't have to create the interface completely, but just edit a current theme. (http://freewpthemes24.com/reesemag/167)
There are 4 basic templates for the site.

1. Homepage
2. Product List Page
3. Product Detail Page
4. General Info Page


The eCommerce plugin we will use is wp-ecommerce (instinct.co.nz).  It's pretty simple. 

Thanks
