Creating Bill of material for a simple electronic product

I am seeking assistance with creating a bill of materials for a simple electronic product. The materials required are mechanical parts, but I am able to procure them myself. Assembly techniques are not a concern at this moment; however, I may need guidance in the future. The successful freelancer must have experience working with bill of materials, be able to explain all necessary materials needed. The right candidate should also have excellent organizational, communication and problem-solving skills. If you have any questions, please don't hesitate to get in touch.
