Build a 3D model of woman for 3D printing and pictures

I need a 3d model created. I need to be a woman bent over. See attachment "Posture" for how she should be standing. This is going to be going to be a bobble butt, instead of a bobblehead. We already have the male created, now we just need a female. This needs to have a spring attached so that the butt can wobble, like the head of a bobblehead, but this is a bobble butt. I want this to be in a 3ds max file as well as 3D printable file. This model should look realistic It should be ethnically ambiguous (Not look like any race in particular) Have a spring connected to the butt or mid-section so that it wobbles Look excellent and sexy (not too cartoonish) The size of the butt should be exaggerated. It should sit on a small platform Wearing sexy clothing (thong, shorts, haltertop ect..) You can do what you think looks best.
