Automatically create a quote based on the 3d model

Looking to be able to take a 3d file and have the ability to automatically create a quote based on the 3d model that is uploaded. For the most part, the app is to read stl's take the top of the file in text turn those od's into volume and then x that by say $4.33 or whatever cubic centimeter. Here are two examples sites that do this: [login to view URL] and [login to view URL] We are looking at shapeways as the way to go. [login to view URL] Files that we want to be able to support: (if possible) Maximum filesize: 64 MB. Supported filetypes: DAE, OBJ, STL, X3D, X3DB, X3DV, WRL, ZIP. ZIP may contain all supported 3d files and textures. Textures files(GIF, JPG, PNG) are only available for color uploads(WRL,X3D,X3DB, X3DV files). Our current site is hosted on wordpress. We are willing to move to any CMS you recommend if needed.
