SOP Manual Creation for Manufacturing Testing

I'm requiring an experienced SOP writer with expertise in the manufacturing industry. The principal goal is to improve the efficiency within the testing operations of our organization. The SOP should feature an overview of the processes involved, containing comprehensive step-by-step instructions. Ideally, the chosen candidate will have a strong background in SOP design, preferably within the manufacturing scene, and boasting an understanding of crafting detailed yet concise procedure manuals. A keen attention to detail is paramount since the document will be used as a reference for our testing operations.
