Hi. I have extensive experience in writing SOPs. My previous employer manufactured chemical products fro a variety of industries, and part of my duties was writing SOPs for our manufacturing group. In addition, I wrote SOPs for using our products in customer-specific applications. I would be happy to do a rewrite for you.
Of course, being a native US English speaker, you can be assured that my sentence structure, grammar,and word usage will be superior to most other bidders.
