Cinema 4D Xpresso Packaging Rig

I need a Cardboard box packaging rig. Using the Xpresso Editor, build a rig that allows the user to punch in sizes for a cardboard box and thickness of the cardboard. The cardboard box has six sides and a material is automatically generated for each face of the package. Each face joins to the corresponding face seamlessly, with perfection. The top and bottom of the package have a slight curve that can be adjusted individually to give the package a sense of realism. The inside of the package has a plain white material applied to it, while the thickness of the cardboard (the edges) has it's own 'off-white' material applied to it which is also editable. If you decide to take on this project, you have very good english speaking and writing skills. I can speak a bit of italian, but not very well. I'm not willing to set a final budget until I see a response and know that the successful applicant can complete the work to my satisfaction. If you're not working in Cinema 4D, then please do not apply.
