Website for a diamond jewellery selling

I am looking for someone to design and build a website for a diamond jewellery selling business. The website should be an e-commerce website, and I have a rough idea of what I would like it to include. I am seeking someone with an expertise in web programming and design who is available to complete the project within a month. With your help, my diamond jewellery business will have a professional, aesthetically pleasing, and user-friendly website that stands out above the competition.
