Design a jewelry website

a new jewelry business start up. Looking for a modern, sleek site with the capacity to sell my pieces online (credit card etc). I have around 50 designed at the moment. It needs to be able to show the pics well. We are a fashionable young company and think that our website should represent us well. This needs to be done quickly ( within the next week.) We have a domain name for the site already. Looking forward to your reply guys.
