I need a professional website done

Hi,

We are looking at making a website which sells different kinds of jewellery. We want it so people can purchase different items off the website and we need the website to look a bit classy. We would be able to supply you with a website which we will be competing against so you can see what there website is like. We hope to be able to have a finished website within 3 weeks. Would be helpful if somebody also has marketing expertise to get traffic to our website once built.
