retail

I have a friend that wants a simple website where she can sell chocolate suckers. She has quite a few customers already and wants a place that they can order they own product(s). Can someone please give me the a couple of ideas (and point me to how-to's) as to best set it up. Originally we thought a site that people can goto that shows retail prices and they can order product, but when they login (login and password) it could show different pricing. Is this a good way of doing wholesale/retail? If it helps all products would be the same for both retail/wholesale.

Nyla Simone Home is an upscale transitional furniture store and full-service showroom. The company needs a website that features, its interior design services, custom furniture products, client testimonials, press/events/blog/newsletter archives, feature event or special item for sale in e-commerce area, as well as be aesthetically pleasing overall. A metropolitan home magazine look is desired.

Site should include the following pages:
Home Page w/ key message (Cosmopolitan Polished Refined) and mission
Products (Beds and Bedding, Furniture, Upholstery, Accessories, Art Gallery)
