3d Model of Gary the Snail Mask with Removable Magnetic Parts

I am seeking a skilled 3D designer to create a detailed digital model of a Gary the Snail mask. The model must include specific features: several parts or compartments that are designed to be removable, utilizing magnetic closures for easy attachment and detachment. The final deliverable should be the digital 3D file only, as I will handle the physical printing independently. Please provide a quote for the modeling work, including the estimated delivery time for the file and the file format you typically deliver in (e.g., stl, obj). Also, let me know if you require a preliminary sketch or reference images before commencing the modeling process. I am looking forward to understanding the approximate cost to ensure it aligns with my budget.
