Development of Magento ecommerce store

I need to get a international ecommerce store done based on magento. The store is going to sell beads, jewelry and gemstones. The store will be inspired by firemountaingems [dot] com. Features of the store will be discussed later. The store design should be simple like this store toobydoo [dot] com I need a magento guru who know what he is doing and design of the site should be very professional.
