Industrial Designer needed to use 3D STL/FBX files and create STP files for production/manufacturing for a Microwave food cover

I am looking for an experienced Industrial Designer who can take 3D STL/FBX files I have ready and create CAD/STP files for production/manufacturing for a Microwave food cover. I do not need any changes to be made to the 3D STL/FBX files and the desired outcome of the project is to produce the CAD/STP Files.
