senor J. , because there is a fair amount of competition in the Detroit area you can get scanning done for $800~$1200 a day. This is using white light systems that produce very accurate and dense STL files for machining. Beware that the files can be pretty big too
Although I work for a distributor of these systems I am not trying to sell you anthing - honest! When I saw the word sculpture it caught my eye because these systems are great for that type of thing. If you want to kill some time you can look around at
www.gom.com or
www.capture3d.com Our customers do work a lot cheaper than we do, I can put you in touch with some of them if you are interested.
