Conversion of stl files to skp file format

You have to use special plugins for SketchUp in order to properly import STL models to the program, but these best works for models that  were previously exported with the program. Probably the easiest choice for stl to skp conversion, although it may be possible in other 3D modeling programs with SketchUp support.
