As I prevously stated I have worked out problematic issues that could of arose."informed me that the latest lasers do not suffer the same problems with errors as they used to"
mmmm, magic lasers that dont reflect on shiny things.
if you do this, make sure the company agrees in writing the quality of model you expect and dont let them off the hook when the cant provide it afterwards. we just has a person scanned. we mistakenly went with the guys who claimed all sorts of quality and cheap price. 3 weeks after the deadline they delivered something that was.. well, laughable.
the guitar will need to be powdered (baby powder and a makeup brush). the powder is a pain to get of bare wood though, so tape off the fretboard and cavities. you should get an "ok" approximation of the body and neck, and from there can make a nice cad model. you wont likely get anything smooth and nice enough to cnc straight off.
in any case, it will be better than hand measuring and if yo get enough people to spread the cost be worth while.
i question what you want to do the with parts and hardware though. youre not gonna get much wothwhile out of a scan of those. too small to pick u accurate details. youre honestly better off measuring and building a solid model.
ive got a new gibson les paul here which i will scan at some point (mostly for the neck profile). its a satin natural finish, so it shouldnt put up too much of a fight. its of course not "historically accurate" for a '59.
