Oil Extraction Deck Copywriter Needed

I have a presentation deck in progress that explains how crude oil is located, drilled, and brought to the surface. I need a writer who can supply clear, technically accurate slide copy that remains understandable to a general-public audience while keeping a formal, informative tone...
