Files conversion

I am looking for a highly skilled individual experienced in the files conversion. I need files converted from OBJ to STEP. The files will be used for 3D prototyping and injection molding. All assignments are time sensitive and must be produced within a specific time period. Prefer someone with at least 5-10 years of experience in this field. Only experienced professionals need apply. If the work is submitted on time and the files are produced as requested, there other projects to follow.
