custom product build module (rings)

I need a PHP-based module that allows a customer to build their own product, in this case engagement rings. There need sto be multiple variables available with each selection made changing the image. For example: --select stone --metal of ring top, --metal of ring bottom --design of top of ring --design of bottom of ring I realize to render this I will need to build a hierarchy of images with available options but I need a system to manage the choices and display, layer the relevant images. This will then generate a composite image and product order which can be completed by the customer. Additional nice to have is that the final image is available for the customer to print from the invoice. More details to qualified clients who have relevant experience with this and can provide their 3 best examples
