Even if you did find a scanning service, wouldn't that just give you the outside shape, with no depth or thickness to the body shell?

I wouldn't pay for a scanning service that doesn't do a complete, real, 3d scan of all sides and surfaces. 
I can get a blob on a platform from photogrammetry.

Your dollars are safe in your pocket, there are not many companies or people who can offer an inside and outside body/surfacing laser scanning service for hobby prices, there is a lot involved in stitching the inside and outside scans together neatly.

Offsetting the outside skin by 1mm is one thing but scanning the inside as well as the outside is another.

Do you know of such services on your side of the pond?
