Need BigCommerce web/graphic designer to edit site template

Dear prospect, I previously operated an e-shop website for my jewelry line, Ali Precious Designs. It turned out that the shopping cart program I was using hacked into my system and corrupted my files:( I got pretty fed up and deleted them. Now, I am starting from scratch using Big Commerce. Although, I do understand html and CSS, I need someone who is a pro to alter the template pages/design for me so I can add and manage the products, myself- ASAP. I design handmade jewelry and accessories so I am not going for the look of a big e-commerce store with multiple brands and text. I need a clean, boutique type feel that is easy to navigate. I have logo options and categories already made. I also have a few .psd mock-up examples you can work with or edit according to your expert design eye.
