DWG conversion

I am looking for a freelancer to assist with a DWG conversion project. Specifically, I need someone to convert 3D models from STL format into DWG. I do not have a specific software requirement for the conversion - any reliable and thorough conversion program will be sufficient. The converted files will be used for manufacturing, so professional accuracy and attention to detail is essential in the conversion process. I look forward to seeing your proposals and selecting the best freelancer for the job.
