Prepare 3D models for printing

I am looking for a person or company to prepare 3D models for printing. Printing will be done using XYZprint software.

Experience working with 3D models and the ability to properly prepare the model for printing is required. The models will be printed using an XYZprinting AiO 3D printer, so it is important that they are properly prepared to achieve the best possible print quality. Printing will be in color, so I need the file to be exported in .obj.

The work can be done remotely, and we will set the rate of payment individually.

A file has been added as an attachment. In the first screenshot you can see how the model looks in SketchUp and in the following pictures how it is read by the XYZprint printing program.
