It doesn't answer your question, but for solutions that address the systemic issue at your organization, I offer two things that have been proven (in my life) to be effective:

First, without hiring more people, I would advise contacting your closest University and ask about graduate faculty who offer grant writing courses. For a small fee, they can provide training and materials for your staff.

Better, though, would be to target a non-technical grant writer and integrate that person into your team. Any communication for an exterior audience would flow through that person. I say non-technical, because that helps you avoid jargon and other "meaningless" items for exterior audiences. I also say specifically grant writer instead of technical writer because technical writers focus on ensuring all material is included, whereas grant writers also ensure that all material is digestible by human people. This person also learns your organization and can help target professional development for folks who might need it - it's all about creating a talent pipeline.

Source: I am a career grant writer, and any technical writing, especially areas as, for lack of a better word, arcane as tech writing can be vastly improved by succinct grant writers. I have contracted for companies in the past, but so few actually want to make systemic changes; mostly they want quick fixes and immediate solutions.
