3d model for 3d printing

I am looking for someone experienced in 3D modeling to create an Artistic Piece in the form of a 3D model. This model should be in OBJ , STL file format and I am open to both smaller pieces (under 10cm) or larger pieces (over 20cm). The piece should be able to be printed using 3D printing technology. A talented individual should be able to help me create a beautiful piece that reflects my project preferences.
