Web page Makeover

Hi, I hired someone to do my website, but have encountered major issues. We use PrestaShop. My website is http://www.dizenos.cl We are looking for someone to help us via Skype, once a week for an hour per service for a couple of months. The idea would be for us to meet to give you an idea of what we want and for you to execute. Problems we are having with the page include the shopping cart, presentation of products, adding prices, adding color selection, design, etc. If you could be of help, let me know and we can schedule a Skype call today to further discuss. I look forward to hearing back from you at your earliest convenience. Sincerely, Andrea
