I've played with photographic imagining, and touch probing, but the fact its time consuming and the results are mixed. I do a little low end mold making, and from time to time I'll have a customer that would like me to cut a mold based on a hand carved or sculpted model. I've emailed several companies on-line who advertise 3D scanning service. Most seem to be more geared towards building size or larger projects, and none have responded.
I'm looking for somebody who is setup to provide decent surface meshes from a model. Most models are going to be less than 12 inches in their largest dimension, and many will not necessarily need to be scanned from all sides. Price is an issue, but regardless of the price I'll just pass it on to the customer. They will either say yes or no and that will be the end of it.
