CAD drawing for a feeding hopper

Hello, I am looking for an experienced CAD drafter familiar with mechanical design to create a 3D CAD drawing of a feeding hopper for my project. I have existing drawings to provide as a reference. We have completed the build of one of these hoppers - photos of the finished hopper are attached. We want to make 16 of these hoppers. Some of them will be bigger than this one, some will be smaller - but they will all be the same basic design.

So will be wanting both CAD drawings, as well as renderings and bill of material

Please let me know if you have any questions. Thank you for considering my project!
