3D models for 3D printers. Personalized figurine

Dear all
I need a 3D model for 3D printer. Final model will be near 30 centimeters. I need 2 file: stl and wrml formats. The minimum wall thickness of 2 mm
Now about the model:
The model is personalized figurine. Head create by photos with any body, such as superman body or person in a suit or with a tennis racket or with a gun (hunting) or on a fishing trip.
As the first model, let's create a model by photos of my face and body - in a classic suit with a bouquet of flowers in the right hand. Something like this picture http://www.dreamstime.com/stock-photo-man-black-suit-flowers-bouquet-wedding-groom-fashion-gray-background-image30292000
In the first model, I want to check the quality of the model, and the quality of 3D printing
After that, we think about regular orders (open shop and sell personalized figurines like http://www.microdwarf.com/index.html) but not caricatures. Realistic 3D models by photographs.
I'm waiting your offers for the price and deadlines for this work.
