Shopify Developer for Custom Visual Product Configurator

We are an established equestrian apparel and tack company seeking an experienced Shopify developer to build an interactive visual product configurator. Customers should be able to customize products such as show jackets, riding boots, helmets and other equestrian items while seeing the product update visually as they make selections. For example, a custom show jacket may include: - Jacket Color - Collar color - Piping collars All selections must be captured with the Shopify order so we know exactly how to manufacture the customer's product. We are not looking for someone who will simply install an existing Shopify configurator app. We want a custom or semi-custom solution that gives us control over the design and functionality and can eventually be expanded to additional products. The configurator must work well on desktop, mobile and large touchscreen display used in our physical/mobile shop. Required experience: -Shopify/ Liquid - Java Script - Custom visual product configurators - Layered PNG/ SVG, Canvas, WebGL or similar visualization methods - Shopify cart/ order properties - Responsive design Experience creating configurators for fashion, footwear, automotive, furniture, sporting goods is a plus. FIRST PROJECT We will begin with ONE product configurator. If the project is successful, we have multiple additional products we would like to develop configurators for. PLEASE INCLUDE WTH YOUR PROPOSAL: 1 - Links to live configurators you have personally built, if available, or video samples 2 - Your recommended technical approach for the Shopify project 3 - Whether you would use layered PNG/SVG images, Canvas/WebGL, or another method and why you choose that one. 4 - Estimated timeline 5- Fixed- price estimate Please do not send only generic Shopify website portfolios. We specifically would like to see examples of interactive visual product customization work. Thank you
