Prestashop Customization

I have a Prestashop installation which needs a fair bit of cutomization. The tasks would include designing and installing custom landing page Designing custom product page Designing custom category page Uploading existing database of products and images We have a large number of products which are custom designed for our customers. So we would need an option or attribute matrix where customers can choose colors and styles for each product. Once we have awarded the project, each of these tasks would be implemented one at a time. You would need to demonstrate a proven history of successful Prestashop installations including urls of sites.
