Custom Product Pricing Structure [Solved]

Does anyone know of a good module that will allow customers to essentially make their own product. Kind of like this website but with even more variation.

If anyone knows of one I would greatly appreciate it! Or if you know how to make one I would love to speak with you. We even have an Excel Mock Up off how we want it to be like.

Thanks in advance!

*Solved by using the awesome CFO module!
