need web store for jewelry website

I need ecommerce capabilities for my jewelry website colletteishiyama.com. Priority is getting it up and running as soon as possible and fitting within the theme of my site, also need to easily be able to update it with new inventory listings myself. Open to it either integrating with my current host lunarpages.com or on a separate provider like bigcartel.com. Candidates who wish to be considered must submit a resume, relevant work examples and references.
