Looking for a basic e-commerce site

Hello:

I would like to have a small e-commerce website created that is simple and clean and was wondering how much this might cost. Please PM me if this is something that you'd like to quote on. I'd be interested in seeing examples of your work.

I'd like to be able to maintain the website myself.

I would also like to have a forum for the site for customers to provide feedback and discuss our offerings.

Thanks,
Ken
