    Hi Andrew, I do CNC work, primarily what is called 2 1/2d in the
    industry, and use Rhino 3d and Mastercam. I specialize in
    micro-machining and engraving with very small mills (.030" to .005"
    diameter). 

    The $900 price seems not entirely unreasonable to me for a 3d
    model...I could easily see spending 3 or 4 days to get it just right.
    How many do you want? The problem with this kind of work is that the
    first one costs a million dollars and the second costs $100. 

    2d techniques are faster but you may or may not get the result
    you're looking for. If you take a digital photo or scan the carving,
    you are just capturing the front and not the sides of the object. 

    In any case since you are going to represent the carving on a
    medallion, it won't be possible to show the same amount of
    relief...obviously a coin or medallion cannot reproduce a bust
    without losing some information. Obviously the customer's
    expectations are extremely important...presumably they understand
    this...do they expect to see just the front of the carving? 

Tom
