STL 3D File Cleanup/Prep for Printing

Hello! I'm looking to hire a freelancer with experience in 3D file cleanup and preparation for printing. The file format I need prepped is STL. The successful freelancer should have past work relevant to this project, and should submit a detailed proposal that includes examples of their past work. I will be using FDM printing technology for this project. The file was generated by using a Creality 3D scanner. It will need to be adjusted to remove some of the abnormalities generated during the scanning process, and to thicken some of the flat surfaces for durability. I'd like to work with a 3D modeler to adjust two files (a left and right cover).
