Not sure if this exist.... but is there any kind of specialist, doctor, scan, etc  out there that can take exact  measurements of height, sitting height, femur length, tibia length, humerus length, etc etc...?

I'd like to save money to get my femur and tiabias done in about 2 years when I can actually get time out of my business, but trying to figure out what my ratios might be like.

Cheers
